status - integerfield(choices:1,2 or 3, default=1) text -charfield and pub_date - datetime field

not solved only with an else? what I mention on the part of the queryset also depends on an else

Elizaveta

I didn't solve how to display link to change question depending on it's state

I didn't solve how to display link to change question depending on it's state

and with an else depending on another state?

Elizaveta

it doesn't work with if either

8

then it would do if for each condition or find a pattern

Elizaveta

I just don't know how to get access to that 'state' field inside this class

8

with .dict can see all propiertis with their names or ways of obtaining them

8

'dict' without quotation marks

class QuestionAdmin(admin.ModelAdmin): fields = ['question_text',] inlines = [ChoiceInline] actions = [make_active, make_closed, make_new, delete_selected] if 'state' == 1 or 'state' == 2: list_display_links = ['question_text',] list_display = ['question_text', 'state', 'pub_date']

what are you tryin to do?

inchidi

what is state? its saved data? or post data?

Elizaveta

In django admin I have all questions displayed. All questions have 3 states - 1,2 and 3. So if the state is 1 or 2 - I will not be able to change the question Question - class, state - integerfield

inchidi

so its saved data right?

Elizaveta

yes

inchidi

so getting Question.objects.get(class=...) is possible

inchidi

but we need to know the class object or just the id

inchidi

class QuestionAdmin(admin.ModelAdmin): fields = ['question_text',] inlines = [ChoiceInline] actions = [make_active, make_closed, make_new, delete_selected] if 'state' == 1 or 'state' == 2: list_display_links = ['question_text',] list_display = ['question_text', 'state', 'pub_date']

i will give you the shortcut, you can leave it like this class QuestionAdmin(admin.ModelAdmin): fields = ['question_text',] inlines = [ChoiceInline] actions = [make_active, make_closed, make_new, delete_selected] ist_display_links = ['question_text',] list_display = ['question_text', 'state', 'pub_date']

inchidi

then you override get_list_display_links methon in this class

inchidi

will looks like this: class QuestionAdmin(admin.ModelAdmin): .... def get_list_display_links(self, request, list_display): if 'state' == 1 or 'state' == 2: return self.list_display_links else: return list(list_display)[:1]

Elizaveta

Thank you! I will try it

inchidi

Thank you! I will try it

it will not work yet until you implement something like this https://stackoverflow.com/a/27304574/3925477 to get your Question

So it will just take the primary key from school, which is the id in django

i know it's the id is the default but in my case it's the name of the school which appear in data base

Anonymous

Sec-school is name of school not id number

just like what Will said. its not, if you get Students object student = Students.objects.get(name="valid name") and print student.school it will print School object by default. but if you override magic method __str__ for School model and you returning name return self.name in that def __str__(self): then print(student.school) will print School name and not School object

i use __str__ to return those values, but my question is about why this foriegh jey takes the name of the school while i never specified it, what if i have two primary keys in the modlel School ?

And I got into things just a couple of weeks ago. And regarding sql, you can learn the basic architecture of sql just more clarity of what you are doing.

you can try delete the __str__ function of School model and see the page again

two primary keys is equals with unique_together in django models meta class

at least name should be primary key in School so it refer it automatically

inchidi

how is your admin in your admin.py looks like?

Anonymous

from django.contrib import admin from first_app.models import School, Students # Register your models here. admin.site.register(School) admin.site.register(Students)

Anonymous

class School(models.Model): name = models.CharField(max_length=265) principal = models.CharField(max_length=256) location = models.CharField(max_length=256) class Students(models.Model): name = models.CharField(max_length=256) age = models.PositiveIntegerField() school = models.ForeignKey(School)

in str for the class School

Anonymous

you are returning the name of the model

Anonymous

consequently this will refer to the attribute name whenever you call School

Anonymous

means i should delete __str__ from School too ?

Anonymous

Yup and that what @DimasInchidi told you to do, what have not you done that ?
