Own fields? about admingeneratorgeneratorbundle

[cedriclombardot]

First of all i invite you to read : http://symfony2admingenerator.org/documentation/form-advanced.html#choose-your-types

You have to ways to overwrite the type of a field by php overwriting the build method or by yaml.

Yaml is more fun :D so in your yaml so write something like that :

edit:
  fields:
    text_type:
      formType: choice
      formOptions:
         choices:
            text: A simple text
            html: With a html editor

Of course for file and wysiwyg its the same.

If your wysiwyg require js read :http://symfony2admingenerator.org/documentation/form.html#overwrite-the-rendering-of-a-field

Thank for choices, this is what I need... Add in the documentation please.

For a file (preview_img) as I understand these steps:

• Add a html to the template "NamespaceYourBundle: (Edit | New): index.html.twig"

  {% block form_preview_img%}
  {{parent ()}}

  {% endblock%}

• Overloaded method updateAction in EditController
  ???

[cedriclombardot]

No for the file :

edit:
  fields:
    image:
      formType: file
      formOptions: []

And in updateAction

<?php 

///....
    public function updateAction($id)
    {
        //....
            $this->saveObject(${{ builder.ModelClass }});

            // Add this http://symfony.com/doc/current/reference/forms/types/file.html
            $form['image']->getData()->move($dir, $someNewFilename);

            $this->get('session')->setFlash('success', 'The object was successfully saved');

            //....
    }

I'll add a postSave($form, ${{ builder.ModelClass }}) method to ease overriding this action

If you want a preview :

{% block form_image %}
<div class="preview">
            {% if MyModel.image  %}
                       <img src="{{ MyModel.image }}" />
            {% endif %}
</div>
{{ parent() }} {# parent() show the content of the autogenerated block #}
{% endblock %}

---

For the HTML editor :

{% block form_html %}
{{ parent() }} 
<srcipt>
// The js to load the editor
</script>
{% endblock %}

Thanks, I'll try your version

[cedriclombardot]

I just add a postSave method

[suncat2000]

Thank, tomorrow will try to use

[suncat2000]

For file field i add uload method in my model (entity).

 ...
 public function upload()
{
    if(null != $this->preview_img){
        $previewImgName = uniqid().'.'.$this->preview_img->guessExtension();
        $this->preview_img->move($this->getUploadRootDir(), $previewImgName);
        $this->preview_img = $previewImgName;
    }
}

...

and overload updateAction in EditController:

...
    if ($form->isValid()) {
        $Text->upload();
        $this->saveObject($Text);
        $this->postSave($form, $Text);

can add method beforeSave(\Entity $val) before calling:

 ...
 $this->beforeSave($Text); 
 $this->saveObject();
 ...

so i can immediately write to the database a new file name

[cedriclombardot]

I have added a preSave() method with the same signature than postSave() but i think that you should move the picture only if there is non db exception on save() so i recommend you to calculate the image path on preSave() and to move it on postSave()

Thanks...
Another little problem, how to make a field file is not required?

[cedriclombardot]

set the form option with the yaml parameter formOptions or addFormOptions with the parameter required: false

fields:
  file:
    addFormOptions:
       required: false

[suncat2000]

It works, i not properly declared 'require' property
