Short Text Field for Django

A very simple Django app that adds a ShortTextField model field class, which is treated like a TextField in the database (i.e. the data is stored in the database with the text rather than the varchar type, and the developer does not need to specify a max_length), but like a CharField in forms (i.e. it uses a single-line input). This is ideal for PostgreSQL, which recommends the 'text' type in a wider variety of circumstances than other commonly-used database backends (see the [PostgreSQL docs] (https://www.postgresql.org/docs/9.1/static/datatype-character.html)).

Usage

  1. Add 'short_text_field' to your INSTALLED_APPS setting like this:

    INSTALLED_APPS = [
        ...
          'short_text_field',
    ]
    
  2. Add a ShortTextField to a model like this:

    from short_text_field.models import ShortTextField
    
    ...
    
      class ExampleModel(models.Model):
            ...
            example_field = ShortTextField
    
  3. A model with a ShortTextField should be registered in the admin site using short_text_field.admin.ModelAdmin.

    admin.site.register(ExampleModel, short_text_field.admin.ModelAdmin)
    

    A subclass of this class will also work:

    class ExampleModelAdmin(short_text_field.admin.ModelAdmin):
        model = ExampleModel
        ...
    
    admin.site.register(ExampleModel, ExampleModelAdmin)
    

    If you have a hierarchy of ModelAdmin subclasses, you can still incorporate short_text_field.admin.ModelAdmin easily as a mixin:

    class ExampleModelAdmin2(short_text_field.admin.ModelAdmin, ExampleModelAdmin1):
        model = ExampleModel
        ...
    
    admin.site.register(ExampleModel, ExampleModelAdmin)
    

    You can also use a subclass of short_text_field.admin.AdminSite for the site, which will make short_text_field.admin.ModelAdmin the default ModelAdmin subclass to use for registering. In the simplest case, you can just set the default_site attribute of the AdminConfig class and then register all of your models in the normal way:

    from django.contrib.admin import apps
    import short_text_field.admin.AdminSite
    
    ...
    
    class ExampleAdminConfig(apps.AdminConfig):
        ...
        default_site = short_text_field.admin.AdminSite
