Form Fields¶

The following can be imported from django_mysql.forms.

SimpleListField¶

class django_mysql.forms.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 django_mysql.forms.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.

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 SimpleSetField

>>> class NumberSetForm(forms.Form):
...     numbers = SimpleSetField(forms.IntegerField())
...

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

>>> form = NumberSetForm({"numbers": "1,2,a"})
>>> form.is_valid()
False

max_length¶: This is an optional argument which validates that the set does not exceed the given length.

min_length¶: This is an optional argument which validates that the set reaches at least the given length.
