Project description
django_param provides ParamForm class which allows python param to be used in django form.
Quick start
Add ‘colorfield’, ‘django_select2’, ‘django_param’ and ‘django.forms’ to your INSTALLED_APPS setting like this:
INSTALLED_APPS = [ ... 'colorfield', 'django_select2', 'django_param', ]
Usage:
# Specify your param class
class MyParam(param.Parameterized):
probability = param.Number(0.5, bounds=(0, 1), doc="Probability that...")
test_string = param.String(default="test string", doc="Your String")
my_param = MyParam()
# Initialize Django Form
django_form = ParamForm({'probability': 0.1, 'test_string': 'test_bound'}, param=my_param)
# Get data from request.POST
django_form = ParamForm(request.POST, param=my_param)
# To return param with values from request.POST
param = django_form.as_param()
Add Form data (assuming your form is named form):
First you need to add the form media, you can include {{ form.media }} in your header page.
To add the form, simply use {{ form }}
you can pass your param to the page and retrieve the values using
{% for p in param.get_param_values %}
<li>{{ p.0 }}: {{ p.1 }}</li>
{% endfor %}
Supported Param Class:
Boolean
Color
CalendarDate
DataFrame
Date
FileSelector
ListSelector
Magnitude
MultiFileSelector
NumericTuple
ObjectSelector
Range
Selector
String
Tuple
XYCoordinates
You can also override any default widget with your own custom widget. For example:
widget_map = {
param.String:
lambda parameterized_object, parameter, name: forms.CharField(
initial=parameterized_object.inspect_value(name) or parameter.default,
widget=Textarea,
),
}
form = ParamForm(param=my_param, widget_map=widget_map)
