Django inline - allow adding disable editing
===

I am asking this question after reading the following questions: [Question_1][1] and [Question_2][2]. Question_1 doesn't have any appropriate answers and Question_2 is having an alternative solution but not a perfect solution.

Here I have two models and admins for them.

**models.py**

	class TaskList(models.Model):
		task_name      = models.CharField(max_length = 255, unique = True)
		description    = models.TextField()
		assignee_role  = models.ForeignKey(Group, related_name = "assignee_roles")
		assignee_name  = models.ForeignKey(User, related_name = "assignee_names")

		def __unicode__(self):
			return "%s" % (self.task_name)

	class TaskComments(models.Model):
		tasklist = models.ForeignKey(TaskList)
		time     = models.DateTimeField(null = True, blank = True)
		comment  = models.TextField()

   	    def __unicode__(self):
			return ""

	    def save(self, *args, **kwargs):
			self.time = datetime.datetime.now()
			super(TaskComments, self).save(*args, **kwargs)


**admin.py**

	class TaskCommentsInlineAdmin(admin.TabularInline):
		model           = TaskComments
		can_delete      = False

	class TaskListAdmin(admin.ModelAdmin):
		inlines      = [TaskCommentsInlineAdmin, ]

		def add_view(self, request, form_url = '', extra_context = None):
			self.readonly_fields = ()
			return super(TaskListAdmin, self).add_view(request, form_url, extra_context)

		def change_view(self, request, form_url = '', extra_context = None):
			self.readonly_fields = ('task_name', 'description', )
			return super(TaskListAdmin, self).change_view(request, form_url, extra_context)

Here the model **TaskComments** is being used as inline in **TaskList**.

**SCENARIO 1**

Here what I want to achieve is:

**When Adding task comments**

 - Hide the field "time"
 - Able to type "comments" and save.

**When opening after saving comments**

 - Both "Time" and "Comments" field should be visible and readonly for already added comments.
 - Able to add comments with the "Time" field hidden.

**SCENARIO 2**

 - Same as previous scenario.
 - The only addition is, the comment should be editable for the user who added it and readonly for all other users. (I will be able to update and get the user who adds the comment).

These are the things I would like to achieve. I have tried using **add_view** and **change_view** in admin. But they are not working for inline. Please provide a solution to achieve these things. Thanks in advance.
