view queryset object in admin view

# Je voudrais, dans ma vue admin, avoir un affichage clair des maintenances

# effectuées, qui corresponde à __unicode__ définie dans Ordi

# mais j'ai :  

In admin view, I would like to get a clear list of results,

as defined in __unicode__ from class User.

Instead, I get:

<bound method User.__unicode__ of <User:  Jean Dubois>>

I just need Jean Dubois..

Here's the code:

#In models.py:


class PC(models.Model):
 def users(self):
 pc = self.user_set.all()
 for o in pc:
 return o.__unicode__
         def __unicode__(self):
                 return 'pc '+unicode(self.id)+' - '+self.os()




class User(models.Model):
    mypc = models.ForeignKey(PC)
    def __unicode__(self):
        return self.name      


#In admin.py:


class PcAdmin(admin.ModelAdmin):
    list_display = ('users','id')

Hello,

Sorry for the previous send unattended...

I have problems trying to print values of a QUerySet Object in Admin View.

In admin view, I would like to get a clear list of results,

as defined in __unicode__ from class User.

Instead, I get:

<bound method User.__unicode__ of <User:  Jean Dubois>>

I just need Jean Dubois..

Here's the code:

#In models.py:


class PC(models.Model):
 def users(self):
 pc = self.user_set.all()
 for o in pc:
 return o.__unicode__
         def __unicode__(self):
                 return 'pc '+unicode(self.id)+' - '+self.os()




class User(models.Model):
    mypc = models.ForeignKey(PC)
    def __unicode__(self):
        return self.name      


#In admin.py:


class PcAdmin(admin.ModelAdmin):
    list_display = ('users','id')

Thanks for your help.

Well, your class User doesn't have an attribute name you are using on the method __unicode__, you should define and set the attribute name with something like a textfield

Hello,

thanks for reply,

of course attribute name was defined, I just ommited to past it!

Here's code:

[code]

#In models.py:


class PC(models.Model):
    def users(self):

        pc = self.user_set.all()

        for o in pc:
            return o.__unicode__
    def __unicode__(self):
        return 'pc '+unicode(self.id)+' - '+self.os()


class User(models.Model):

    name=models.TextField()
    mypc = models.ForeignKey(PC)

    def __unicode__(self):
        return self.name       


#In admin.py:


class PcAdmin(admin.ModelAdmin):
    list_display = ('users','id')

[/code]

Still have this weird print: 

<bound method User.__unicode__ of <User:  Jean Dubois>>

instead of:

Jean Dubois

thank you for help

Hi, there are several flaws in your code.

Here you return first (only first) __unicode__ method of "o" object.
Wild guess is that you want to do something like this:

def users(self):
return u', '.join([unicode(u) for u in self.user_set.all()]) ## Return comma separated list of users

> def __unicode__(self):
> return 'pc '+unicode(self.id)+' - '+self.os()

You declare unicode method, yet your return is a bytestring. You should put u-prefix before texts.

That's correct output - first object and it's __unicode__ method - that's what you return in your code.

I made a clearer and full sample code.

When I use the code as is, I get results in a poor readable

format in PCAdmin view

[<User: jean dubois>, <User: martin franck>]

although I just want Jean Dubois, martin franck

Thanks for help

My models.py

[code]

from django.db import models

class PC(models.Model):

os= models.CharField(max_length=5, null=True, blank=True)

def users(self):

pc = self.user_set.all()

return pc

# If I use loop "for", I get a great unicode view, but only the first result...

# for o in pc:

# return o.__unicode__()

def __unicode__(self):

return 'pc  '+ unicode(self.id)+ ' - ' + self.os

class User(models.Model):

    name=models.CharField(max_length=20, null=True, blank=True)

    mypc = models.ForeignKey(PC, null=True,blank=True)

    def __unicode__(self):

        return self.name

[/code]

My admin.py:

[code]

from django.contrib import admin

from users.models import User, PC

class PCAdmin(admin.ModelAdmin):

    list_display = ('users','id')

    

class UserAdmin(admin.ModelAdmin):  

list_display = ('name','mypc')

admin.site.register(User, UserAdmin)

admin.site.register(PC, PCAdmin)

/]
