'''Adds a Recipe
This view follows the create/update pattern for CRUD forms. A GET request
returns an empty recipe form, ingredient formset, and recipe_step formset.
A valid post creates the recipe object, builds the step and ingredient
objects from their respective formsets, and adds the foreign keys
references to the recipe. If the forms are not all valid, the function
returns attached references to all the forms/formsets. Finally, a GET
request with a valid recipe pk will return an attached form/formset for
updating the recipe.
Args:
request: the standard django.http.HttpRequest for all views
Returns:
django.http.HttpResponse with a context containing a recipe_form,
ingredient_formset and recipe_step_formset, or a redirect to the
list of recipes
Raises:
django.http.Http404: recipe_id was given, but not a valid Recipe object
