Using Django time date widgets in custom form

Question

How can I use the nifty JavaScript date and time widgets that the default admin uses with my custom view   I have looked through the Django forms documentation  and it briefly mentions django contrib admin widgets  but I don t know how to use it   Here is my template that I want it applied on    lt form action     method  POST  gt       lt table gt             for f in form                lt tr gt   lt td gt     f name    lt  td gt   lt td gt    f    lt  td gt   lt  tr gt             endfor         lt  table gt       lt input type  submit  name  submit  value  Add Product  gt   lt  form gt    Also  I think it should be noted that I haven t really written a view up myself for this form  I am using a generic view  Here is the entry from the url py    r  admin products add     create object    model   Product   post save redirect           And I am relevantly new to the whole Django MVC MTV thing  so please go easy

Here s another 2020 solution  inspired by  Sandeep s  Using the MinimalSplitDateTimeMultiWidget found in this gist  in our Form as below  we can use modern browser date and time selectors  via eg  type    date    We don t need any JS  class EditAssessmentBaseForm forms ModelForm       class Meta          model   Assessment         fields      all         begin   DateTimeField widget MinimalSplitDateTimeMultiWidget

As the solution is hackish  I think using your own date time widget with some JavaScript is more feasible

Starting in Django 1 2 RC1  if you re using the Django admin date picker widge trick  the following has to be added to your template  or you ll see the calendar icon url being referenced through   missing-admin-media-prefix        load adminmedia       At the top of the template         In the head section of the template      lt script type  text javascript  gt  window   admin media prefix         filter escapejs      admin media prefix      endfilter       lt  script gt

What about just assigning a class to your widget and then binding that class to the JQuery datepicker   Django forms py   class MyForm forms ModelForm      class Meta      model   MyModel    def   init   self   args    kwargs       super MyForm  self    init    args    kwargs      self fields  my date field   widget attrs  class      datepicker    And some JavaScript for the template         datepicker   datepicker

The below will also work as a last resort if the above failed  class PaymentsForm forms ModelForm       class Meta          model   Payments      def   init   self   args    kwargs           super PaymentsForm  self    init    args    kwargs          self fields  date   widget   SelectDateWidget     Same as   class PaymentsForm forms ModelForm       date   forms DateField widget SelectDateWidget         class Meta          model   Payments   put this in your forms py from django forms extras widgets import SelectDateWidget

Complementing the answer by Carl Meyer  I would like to comment that you need to put that header in some valid block  inside the header  within your template      block extra head      lt link rel  stylesheet  type  text css  href   media admin css forms css   gt   lt link rel  stylesheet  type  text css  href   media admin css base css   gt   lt link rel  stylesheet  type  text css  href   media admin css global css   gt   lt link rel  stylesheet  type  text css  href   media admin css widgets css   gt    lt script type  text javascript  src   admin jsi18n   gt  lt  script gt   lt script type  text javascript  src   media admin js core js  gt  lt  script gt   lt script type  text javascript  src   media admin js admin RelatedObjectLookups js  gt  lt  script gt      form media        endblock

I find myself referencing this post a lot  and found that the documentation defines a slightly less hacky way to override default widgets     No need to override the ModelForm s   init   method   However  you still need to wire your JS and CSS appropriately as Carl mentions   forms py  from django import forms from my app models import Product from django contrib admin import widgets                                          class ProductForm forms ModelForm       mydate   forms DateField widget widgets AdminDateWidget      mytime   forms TimeField widget widgets AdminTimeWidget      mydatetime   forms SplitDateTimeField widget widgets AdminSplitDateTime       class Meta          model   Product   Reference Field Types to find the default form fields

The growing complexity of this answer over time  and the many hacks required  probably ought to caution you against doing this at all  It s relying on undocumented internal implementation details of the admin  is likely to break again in future versions of Django  and is no easier to implement than just finding another JS calendar widget and using that   That said  here s what you have to do if you re determined to make this work    Define your own ModelForm subclass for your model  best to put it in forms py in your app   and tell it to use the AdminDateWidget   AdminTimeWidget   AdminSplitDateTime  replace  mydate  etc with the proper field names from your model    from django import forms from my app models import Product from django contrib admin import widgets                                         class ProductForm forms ModelForm       class Meta          model   Product     def   init   self   args    kwargs           super ProductForm  self    init    args    kwargs          self fields  mydate   widget   widgets AdminDateWidget           self fields  mytime   widget   widgets AdminTimeWidget           self fields  mydatetime   widget   widgets AdminSplitDateTime    Change your URLconf to pass  form class   ProductForm instead of  model   Product to the generic create object view  that ll mean  from my app forms import ProductForm  instead of  from my app models import Product   of course   In the head of your template  include    form media    to output the links to the Javascript files  And the hacky part  the admin date time widgets presume that the i18n JS stuff has been loaded  and also require core js  but don t provide either one automatically   So in your template above    form media    you ll need    lt script type  text javascript  src   my admin jsi18n   gt  lt  script gt   lt script type  text javascript  src   media admin js core js  gt  lt  script gt    You may also wish to use the following admin CSS  thanks Alex for mentioning this     lt link rel  stylesheet  type  text css  href   media admin css forms css   gt   lt link rel  stylesheet  type  text css  href   media admin css base css   gt   lt link rel  stylesheet  type  text css  href   media admin css global css   gt   lt link rel  stylesheet  type  text css  href   media admin css widgets css   gt     This implies that Django s admin media  ADMIN MEDIA PREFIX  is at  media admin  - you can change that for your setup   Ideally you d use a context processor to pass this values to your template instead of hardcoding it  but that s beyond the scope of this question   This also requires that the URL  my admin jsi18n  be manually wired up to the django views i18n javascript catalog view  or null javascript catalog if you aren t using I18N    You have to do this yourself instead of going through the admin application so it s accessible regardless of whether you re logged into the admin  thanks Jeremy for pointing this out    Sample code for your URLconf    r  my admin jsi18n    django views i18n javascript catalog      Lastly  if you are using Django 1 2 or later  you need some additional code in your template to help the widgets find their media      load adminmedia       At the top of the template         In the head section of the template      lt script type  text javascript  gt  window   admin media prefix         filter escapejs      admin media prefix      endfilter       lt  script gt    Thanks lupefiasco for this addition

For Django    2 0     Note  Using admin widgets for date-time fields is not a good idea as admin style-sheets can conflict with your site style-sheets in case you are using bootstrap or any other CSS frameworks  If you are building your site on bootstrap use my bootstrap-datepicker widget django-bootstrap-datepicker-plus    Step 1  Add javascript-catalog URL to your project s  not app s  urls py file   from django views i18n import JavaScriptCatalog  urlpatterns         path  jsi18n   JavaScriptCatalog as view    name  javascript-catalog        Step 2  Add required JavaScript CSS resources to your template    lt script type  text javascript  src     url  javascript-catalog      gt  lt  script gt   lt script type  text javascript  src     static   admin js core js      gt  lt  script gt   lt link rel  stylesheet  type  text css  href     static   admin css widgets css      gt   lt style gt  calendar gt table gt caption caption-side unset  lt  style gt  lt  --caption fix for bootstrap4-- gt     form media              Form required JS and CSS      Step 3  Use admin widgets for date-time input fields in your forms py   from django contrib admin import widgets from  models import Product  class ProductCreateForm forms ModelForm       class Meta          model   Product         fields     name    publish date    publish time    publish datetime           widgets                  publish date   widgets AdminDateWidget               publish time   widgets AdminTimeWidget               publish datetime   widgets AdminSplitDateTime
