57 | =head1 DESCRIPTION |
58 | |
cca5cd98 |
59 | This portion of the tutorial explores L<HTML::FormFu|HTML::FormFu> and |
60 | how it can be used to manage forms, perform validation of form input, |
ab0db558 |
61 | as well as save and restore data to/from the database. This was written |
2314f851 |
62 | using HTML::FormFu version 0.05001. |
cca5cd98 |
63 | |
64 | See |
3ab6187c |
65 | L<Catalyst::Manual::Tutorial::09_AdvancedCRUD|Catalyst::Manual::Tutorial::09_AdvancedCRUD> |
cca5cd98 |
66 | for additional form management options other than |
67 | L<HTML::FormFu|HTML::FormFu>. |

70 | =head1 HTML::FormFu FORM CREATION |
cca5cd98 |
71 | |
72 | This section looks at how L<HTML::FormFu|HTML::FormFu> can be used to |
4b4d3884 |
73 | add additional functionality to the manually created form from Chapter 4. |
cca5cd98 |
74 | |
75 | |
8a472b34 |
76 | =head2 Inherit From Catalyst::Controller::HTML::FormFu |
cca5cd98 |
77 | |
78 | First, change your C<lib/MyApp/Controller/Books.pm> to inherit from |
79 | L<Catalyst::Controller::HTML::FormFu|Catalyst::Controller::HTML::FormFu> |
8a7951ae |
80 | by changing the C<use parent> line from the default of: |
cca5cd98 |
81 | |
ab0db558 |
82 | use parent 'Catalyst::Controller'; |
cca5cd98 |
83 | |
84 | to use the FormFu base controller class: |
85 | |
ab0db558 |
86 | use parent 'Catalyst::Controller::HTML::FormFu'; |
cca5cd98 |
87 | |
88 | |
89 | =head2 Add Action to Display and Save the Form |
90 | |
91 | Open C<lib/MyApp/Controller/Books.pm> in your editor and add the |
92 | following method: |
93 | |
d682d02d |
94 | =head2 formfu_create |
cca5cd98 |
95 | |
59d6a035 |
96 | Use HTML::FormFu to create a new book |
cca5cd98 |

99 | |
ccc9b2bc |
100 | sub formfu_create :Chained('base') :PathPart('formfu_create') :Args(0) :FormConfig { |
cca5cd98 |
101 | my ($self, $c) = @_; |
102 | |
103 | # Get the form that the :FormConfig attribute saved in the stash |
104 | my $form = $c->stash->{form}; |
105 | |
166c90a0 |
106 | # Check if the form has been submitted (vs. displaying the initial |
107 | # form) and if the data passed validation. "submitted_and_valid" |
cca5cd98 |
108 | # is shorthand for "$form->submitted && !$form->has_errors" |
109 | if ($form->submitted_and_valid) { |
110 | # Create a new book |
3b1fa91b |
111 | my $book = $c->model('DB::Book')->new_result({}); |
cca5cd98 |
112 | # Save the form data for the book |
aee27483 |
113 | $form->model->update($book); |
cca5cd98 |
114 | # Set a status message for the user |

116 | # Return to the books list |

117 | $c->response->redirect($c->uri_for($self->action_for('list'))); |
cca5cd98 |
118 | $c->detach; |
9cb64a37 |
119 | } else { |
120 | # Get the authors from the DB |
3b1fa91b |
121 | my @author_objs = $c->model("DB::Author")->all(); |
9cb64a37 |
122 | # Create an array of arrayrefs where each arrayref is an author |
123 | my @authors; |
acbd7bdd |
124 | foreach (sort {$a->last_name cmp $b->last_name} @author_objs) { |
9cb64a37 |
125 | push(@authors, [$_->id, $_->last_name]); |
126 | } |
127 | # Get the select added by the config file |
128 | my $select = $form->get_element({type => 'Select'}); |
129 | # Add the authors to it |
130 | $select->options(\@authors); |
131 | } |
132 | |
cca5cd98 |
133 | # Set the template |
d682d02d |
134 | $c->stash->{template} = 'books/formfu_create.tt2'; |
cca5cd98 |
135 | } |
136 | |
137 | |
138 | =head2 Create a Form Config File |
139 | |
140 | Although C<HTML::FormFu> supports any configuration file handled by |
141 | L<Config::Any|Config::Any>, most people tend to use YAML. First |
142 | create a directory to hold your form configuration files: |
143 | |
144 | mkdir -p root/forms/books |
145 | |
d682d02d |
146 | Then create the file C<root/forms/books/formfu_create.yml> and enter the |
cca5cd98 |
147 | following text: |
148 | |
149 | --- |
9cb64a37 |
150 | # indicator is the field that is used to test for form submission |
cca5cd98 |
151 | indicator: submit |
9cb64a37 |
152 | # Start listing the form elements |
cca5cd98 |
153 | elements: |
9cb64a37 |
154 | # The first element will be a text field for the title |
cca5cd98 |
155 | - type: Text |
156 | name: title |
157 | label: Title |
9cb64a37 |
158 | # This is an optional 'mouse over' title pop-up |
cca5cd98 |
159 | attributes: |
160 | title: Enter a book title here |
d682d02d |
161 | |
162 | # Another text field for the numeric rating |
cca5cd98 |
163 | - type: Text |
164 | name: rating |
165 | label: Rating |
166 | attributes: |
167 | title: Enter a rating between 1 and 5 here |
d682d02d |
168 | |
169 | # Add a drop-down list for the author selection. Note that we will |
170 | # dynamically fill in all the authors from the controller but we |
171 | # could manually set items in the drop-list by adding this YAML code: |
172 | # options: |
173 | # - [ '1', 'Bastien' ] |
174 | # - [ '2', 'Nasseh' ] |
175 | - type: Select |
176 | name: authors |
177 | label: Author |
178 | |
9cb64a37 |
179 | # The submit button |
cca5cd98 |
180 | - type: Submit |
181 | name: submit |
182 | value: Submit |
183 | |
0171092f |
184 | B<NOTE:> Copying and pasting YAML from perl documentation is sometimes |
1fba2369 |
185 | tricky. See the L<Config::General Config for this tutorial> section of |
186 | this document for a more foolproof config format. |
0171092f |
187 | |
cca5cd98 |
188 | |
189 | =head2 Update the CSS |
190 | |
ab0db558 |
191 | Edit C<root/static/css/main.css> and add the following lines to the bottom of |
cca5cd98 |
192 | the file: |
193 | |
acbd7bdd |
194 | ... |
d682d02d |
195 | input { |
cca5cd98 |
196 | display: block; |
197 | } |
d682d02d |
198 | select { |
cca5cd98 |
199 | display: block; |
200 | } |
d682d02d |
201 | .submit { |
202 | padding-top: .5em; |
203 | display: block; |
cca5cd98 |
204 | } |
205 | |
d682d02d |
206 | These changes will display form elements vertically. Note that the |
207 | existing definition of the C<.error> class is pulling the color scheme |
208 | settings from the C<root/lib/config/col> file that was created by the |
209 | TTSite helper. This allows control over the CSS color settings from a |
210 | single location. |
cca5cd98 |
211 | |
212 | |
213 | =head2 Create a Template Page To Display The Form |
214 | |
d682d02d |
215 | Open C<root/src/books/formfu_create.tt2> in your editor and enter the following: |
cca5cd98 |
216 | |
217 | [% META title = 'Create/Update Book' %] |
218 | |
219 | [%# Render the HTML::FormFu Form %] |
220 | [% form %] |
221 | |
e075db0c |
222 | <p><a href="[% c.uri_for(c.controller.action_for('list')) %]">Return to book list</a></p> |
cca5cd98 |
223 | |
224 | |
225 | =head2 Add Links for Create and Update via C<HTML::FormFu> |
226 | |
227 | Open C<root/src/books/list.tt2> in your editor and add the following to |
228 | the bottom of the existing file: |
229 | |
acbd7bdd |
230 | ... |
cca5cd98 |
231 | <p> |
232 | HTML::FormFu: |
e075db0c |
233 | <a href="[% c.uri_for(c.controller.action_for('formfu_create')) %]">Create</a> |
cca5cd98 |
234 | </p> |
235 | |
d682d02d |
236 | This adds a new link to the bottom of the book list page that we can |
237 | use to easily launch our HTML::FormFu-based form. |
238 | |
cca5cd98 |
239 | |
8a472b34 |
240 | =head2 Test The HTML::FormFu Create Form |
cca5cd98 |
241 | |
242 | Press C<Ctrl-C> to kill the previous server instance (if it's still |
243 | running) and restart it: |
244 | |
245 | $ script/myapp_server.pl |
246 | |
0909d46f |
247 | Login as C<test01> (password: mypass). Once at the Book List page, |
248 | click the new HTML::FormFu "Create" link at the bottom to display the |
3b1fa91b |
249 | form. Fill in the following values: |
d682d02d |
250 | |
2314f851 |
251 | Title: Internetworking with TCP/IP Vol. II |
252 | Rating: 4 |
253 | Author: Comer |
3b1fa91b |
254 | |
255 | Click the Submit button, and you will be returned to the Book List page |
256 | with a "Book created" status message displayed. |
257 | |
258 | Also note that this implementation allows you to create books with any |
d682d02d |
259 | bogus information. Although we have constrained the authors with the |
59d6a035 |
260 | drop-down list (note that this isn't bulletproof because we still have |
261 | not prevented a user from "hacking" the form to specify other values), |
262 | there are no restrictions on items such as the length of the title (for |
3b1fa91b |
263 | example, you can create a one-letter title) and the value of the rating |
59d6a035 |
264 | (you can use any number you want, and even non-numeric values with |
265 | SQLite). The next section will address this concern. |
cca5cd98 |
266 | |
267 | B<Note:> Depending on the database you are using and how you established |
268 | the columns in your tables, the database could obviously provide various |
269 | levels of "type enforcement" on your data. The key point being made in |
270 | the previous paragraph is that the I<web application> itself is not |
271 | performing any validation. |
272 | |
273 | |
8a472b34 |
274 | =head1 HTML::FormFu VALIDATION AND FILTERING |
cca5cd98 |
275 | |
d682d02d |
276 | Although the use of L<HTML::FormFu|HTML::FormFu> in the previous section |
277 | did provide an automated mechanism to build the form, the real power of |
278 | this module stems from functionality that can automatically validate and |
279 | filter the user input. Validation uses constraints to be sure that |
280 | users input appropriate data (for example, that the email field of a |
281 | form contains a valid email address). Filtering can also be used to |
282 | remove extraneous whitespace from fields or to escape meta-characters in |
283 | user input. |

285 | |
d682d02d |
286 | =head2 Add Constraints |
cca5cd98 |
287 | |
d682d02d |
288 | Open C<root/forms/books/formfu_create.yml> in your editor and update it |
cca5cd98 |

378 | The main changes are: |
379 | |
380 | =over 4 |
381 | |
382 | =item * |
383 | |
384 | The C<Select> element for C<authors> is changed from a single-select |
385 | drop-down to a multi-select list by adding configuration for the |
386 | C<multiple> and C<size> options in C<formfu_create.yml>. |
387 | |
388 | =item * |
389 | |
390 | Constraints are added to provide validation of the user input. See |
391 | L<HTML::FormFu::Constraint|HTML::FormFu::Constraint> for other |
392 | constraints that are available. |
393 | |
394 | =item * |
395 | |
396 | A variety of filters are run on every field to remove and escape |
397 | unwanted input. See L<HTML::FormFu::Filter|HTML::FormFu::Filter> |
398 | for more filter options. |

406 | running) and restart it: |
407 | |
408 | $ script/myapp_server.pl |
409 | |
59d6a035 |
410 | Make sure you are still logged in as C<test01> and try adding a book |
411 | with various errors: title less than 5 characters, non-numeric rating, a |
412 | rating of 0 or 6, etc. Also try selecting one, two, and zero authors. |
413 | When you click Submit, the HTML::FormFu C<constraint> items will |
414 | validate the logic and insert feedback as appropriate. Try adding blank |
415 | spaces at the front or the back of the title and note that it will be |
416 | removed. |
417 | |
418 | |
419 | =head1 CREATE AND UPDATE/EDIT ACTION |
420 | |
421 | Let's expand the work done above to add an edit action. First, open |
422 | C<lib/MyApp/Controller/Books.pm> and add the following method to the |
423 | bottom: |
424 | |
425 | =head2 formfu_edit |

478 | |
479 | Most of this code should look familiar to what we used in the |
480 | C<formfu_create> method (in fact, we should probably centralize some of |
481 | the common code in separate methods). The main differences are: |
482 | |
483 | =over 4 |
484 | |
485 | =item * |
486 | |
ccc9b2bc |
487 | We have to manually specify the name of the FormFu .yml file as an |
488 | argument to C<:FormConfig> because the name can no longer be |
489 | automatically deduced from the name of our action/method (by default, |
490 | FormFu would look for a file named C<books/formfu_edit.yml>). |
59d6a035 |
491 | |
492 | =item * |
493 | |
ccc9b2bc |
494 | We load the book object from the stash (found using the $id passed to |
495 | the Chained object method) |
59d6a035 |
496 | |
497 | =item * |
498 | |
ccc9b2bc |
499 | We use C<$id> to look up the existing book from the database. |
500 | |
501 | =item * |
59d6a035 |
502 | |
ccc9b2bc |
503 | We make sure the book lookup returned a valid book. If not, we set |
504 | the error message and return to the book list. |
2314f851 |
505 | |
59d6a035 |
506 | =item * |
507 | |
508 | If the form has been submitted and passes validation, we skip creating a |
aee27483 |
509 | new book and just use C<$form-E<gt>model-E<gt>update> to update the existing |
59d6a035 |
510 | book. |
511 | |
512 | =item * |
513 | |
514 | If the form is being displayed for the first time (or has failed |
515 | validation and it being redisplayed), we use |
aee27483 |
516 | C<$form-E<gt>model-E<gt>default_values> to populate the form with data from the |
59d6a035 |
517 | database. |
518 | |
519 | =back |
520 | |
521 | Then, edit C<root/src/books/list.tt2> and add a new link below the |
522 | existing "Delete" link that allows us to edit/update each existing book. |
523 | The last E<lt>tdE<gt> cell in the book list table should look like the |
524 | following: |
525 | |
ab0db558 |
526 | ... |
59d6a035 |
527 | <td> |
528 | [% # Add a link to delete a book %] |
acbd7bdd |
529 | <a href="[% c.uri_for(c.controller.action_for('delete'), [book.id]) %]">Delete</a> |
59d6a035 |
530 | [% # Add a link to edit a book %] |
acbd7bdd |
531 | <a href="[% c.uri_for(c.controller.action_for('formfu_edit'), [book.id]) %]">Edit</a> |
59d6a035 |
532 | </td> |
ab0db558 |
533 | ... |
534 | |
535 | B<Note:> Only add two lines (the "Add a link to edit a book" comment |
536 | and the href for C<formfu_edit>). Make sure you add it below the |
537 | existing C<delete> link. |
59d6a035 |
538 | |
539 | |
540 | =head2 Try Out the Edit/Update Feature |
541 | |
542 | Press C<Ctrl-C> to kill the previous server instance (if it's still |
543 | running) and restart it: |
544 | |
545 | $ script/myapp_server.pl |
546 | |
547 | Make sure you are still logged in as C<test01> and go to the |
548 | L<http://localhost:3000/books/list> URL in your browser. Click the |
549 | "Edit" link next to "Internetworking with TCP/IP Vol. II", change the |
550 | rating to a 3, the "II" at end of the title to the number "2", add |
551 | Stevens as a co-author (control-click), and click Submit. You will then |
552 | be returned to the book list with a "Book edited" message at the top in |
553 | green. Experiment with other edits to various books. |

556 | =head2 More Things to Try |
557 | |
558 | You are now armed with enough knowledge to be dangerous. You can keep |
559 | tweaking the example application; some things you might want to do: |
560 | |
561 | =over 4 |
562 | |
563 | =item * |
564 | |
acbd7bdd |
565 | Add an appropriate authorization check to the new Edit function. |
5fe0e6dd |
566 | |
567 | =item * |
568 | |
569 | Cleanup the List page so that the Login link only displays when the user |
570 | isn't logged in and the Logout link only displays when a user is logged |
571 | in. |
572 | |
573 | =item * |
574 | |
575 | Add a more sensible policy for when and how users and admins can do |
576 | things in the CRUD cycle. |
577 | |
578 | =item * |
579 | |
580 | Support the CRUD cycle for authors. |
581 | |
582 | =back |
583 | |
584 | Or you can proceed to write your own application, which is probably the |
585 | real reason you worked through this Tutorial in the first place. |
