Description

GenModelForm is a generic class of Codenerix used to define a form created from a model. This class inherits from django class forms.ModelForm We recomended that the name of each class which inherit from GenModelForm follow this pattern: NameModel+Form.

• Example:

  If model is User, then, GenCreate declarations should be, class UserForm(GenModelForm):

Attribute

Warning GenModelForm inherits from forms.ModelForm, so attributes declaration is a little different than other classes. In GenModelForm all attributes are put into class Meta:

autofill

Autofill is an attribute designed to fill foreignkey attributes with data based in a textbox, other information of the form or an AngularJS function. The structure is a dictionary with the attribute name as key and a list as value. This list consists in the following ordered fields:

• field[0]: Type of the selector that you need to create:
  • select : Show a box that take a single choice.
  • multiselect : Show a box which let you select multiple choices.
• field[1]: Minimum number of letters required in the textbox to start the execution of a search. (If you want to show all records in the textbox you should write ‘*’)
• field[2]: Related name of the GenForeignKey class used to fetch the field data.
• field[3-n]: (Optionals fields) The rest of fields are filters used to send the pk of a the selected attribute. Usually is used to take the value of an attribute and perform the search using it. There is two options to use this filters:
  • attrName: Take actual value, if exist, from a selected attribute.
  • __pk__: Send pk of own object.

autofill = {
    # Search of attr3 based in attr2
    'attr3': ['select', 3, related_name_foreignkey_url,'attr2'],
    # Search based in his own pk.
    'attr5': ['select', 3, related_name_foreignkey_url,'__pk__'],
    # Search based in his own pk and attr2.
    'attr4': ['select', 3, related_name_foreignkey_url,'__pk__', 'attr2'],
}

exclude

Used to exclude attributes from the model that shouldn’t be shown in the view. Available in django

model

Model used to generate the form. Available in django

Method

__groups__(self)

This method is used to define the order and layout of the form fields. Its goal is to be used as an styling tool for the forms.

def __groups__(self):
    groups = [
        (
            _('Group name'), 12,
            ['attr1', 6, '#23fe33', '#005476', 'left', True, _('Alternative label')],
            ['attr2', 6, None, None, True],
            ['attr3', 3],
            ['attr4', 12, None, None, None, None, None, ['ng-change=function()']],
        )
    ]
    return groups

Return

Groups return a list of tuples. Each tuple represent in template a different box. Each tuple have next structure:

• Name of the box.

• Number of columns which the box takes. Remember: max númber of columns it's 12

• From position 2 to the last are a list of options which control how to render each declared field. The structure of the list is:

  • attr[0]: Name of field (Named or not in the model).
  • attr[1]: Number of columns which takes this field.
  • attr[2]: Label color (HTML color code).
  • attr[3]: Padding color (HTML color code).
  • attr[4]: Alignment of the label. Options are (left|center|right)
  • attr[5]: Label and field are in the same line? (Boolean). Is used for checkbox and roundcheck
  • attr[6]: Alternative label. If there is some text specified Codenerix will show it on the template (Default value is None).
  • attr[7]: Extra data. A list of extra data that is sent to template. (Is sended in plain text)

GenModelForm with foreignkey

from codenerix.forms import GenModelForm


class ModelNameForm(GenModelForm):

    class Meta:
        model = ModelName
        exclude = ['attr5']
        # attr3 it's a foreignkey field, and start to search with 3 characters with condition epecified in view of related name.
        autofill = {
            'attr3': ['select', 3, related_name_foreignkey_url, 'attr2'],
        }

    def __groups__(self):
        return [
