Form Fields

The following can be imported from django_mysql.forms.

JSONField

class JSONField[source]

A field which accepts JSON encoded data for a JSONField. It is represented by an HTML <textarea>.

User friendly forms

JSONField is not particularly user friendly in most cases, however it is a useful way to format data from a client-side widget for submission to the server.

SimpleListField

class SimpleListField(base_field, max_length=None, min_length=None)[source]

A simple field which maps to a list, with items separated by commas. It is represented by an HTML <input>. Empty items, resulting from leading, trailing, or double commas, are disallowed.

base_field

This is a required argument.

It specifies the underlying form field for the set. It is not used to render any HTML, but it does process and validate the submitted data. For example:

>>> from django import forms
>>> from django_mysql.forms import SimpleListField

>>> class NumberListForm(forms.Form):
...     numbers = SimpleListField(forms.IntegerField())

>>> form = NumberListForm({'numbers': '1,2,3'})
>>> form.is_valid()
True
>>> form.cleaned_data
{'numbers': [1, 2, 3]}

>>> form = NumberListForm({'numbers': '1,2,a'})
>>> form.is_valid()
False
max_length

This is an optional argument which validates that the list does not exceed the given length.

min_length

This is an optional argument which validates that the list reaches at least the given length.

User friendly forms

SimpleListField is not particularly user friendly in most cases, however it’s better than nothing.

SimpleSetField

class SimpleSetField(base_field, max_length=None, min_length=None)[source]

A simple field which maps to a set, with items separated by commas. It is represented by an HTML <input>. Empty items, resulting from leading, trailing, or double commas, are disallowed.

False
max_length
