#django-admin

Django專案初始設定中有提到,

一個專案可以有一個以上的app,

而且這些app各自獨立並且可以運行在不同的專案中,

今天就來教大家:

  在專案中建立第一個Django app

  使用

django-admin   startproject    project_name 能夠新增一個新的專案,

  而新增app的方式與此類似,

執行:

python   manage.py    startapp    accounts

就能建立一個名為accounts的app,

  建立以後可看如下圖左邊紅色框,

系統已經新增一個app在此專案中,

要在專案中使用此元件的話,

要到專案的settings.py找到INSTALLED_APPS,

將此名為accounts的app加入專案中,

  下圖範例右方的紅色框打字到一半IDE就自動帶出相關的名稱,

(因為一個好的IDE軟體能幫助專案快速開發)

 The custom template tag contains some integration and modification to admin site interface. This doesn't modify the core source code of django but instead it overrides some functionalities in Django app. I will add more functionalities when i have time. Enjoy! 

Steps on applying this into your site. ( Same as applying normal custom templatetags)

Step 1: Copy and paste this `templatetags` directory inside your app ( any app ). It should be recognized by Django or else it will raise an error 'invalid templatetag'

Step 2: Override your admin/index.html. If you don't know how to override the admin( customize ), You can search the net. It's pretty simple though, just add an admin directory to your templates directory and copy&paste the admin templates to that folder. In this case just copy the index.html

Step 3: Load the templatetag. {% load custom_admin %} <-- add this above. or this {% load i18n %} to this {% load i18n custom_admin %}. (you'll know what i mean lol)

Step 4: Add ADMIN_APP_ORDER in settings.py and add the apps(the way you want it to be order).

        ex. ADMIN_APP_ORDER = ('app1','app2','app3')

Step 5: No step 5. run it and check if it works. If not I'm sorry bro i failed you.

* Note: The current tag will only re-order the apps in index.html but not the models inside the app but I will updated it with cooler stuff when i have time. You can edit it though. thanks!

I wanted to show the image chosen on the UserProfile inline section of the user model for the admin and also on the change list of the admin so heres what I did:

I changed the models.ImageField to sorl ImageField on the model.py of User profile like this

    from sorl.thumbnail import ImageField

    class UserProfile(BaseModel):

    [...]

        photo = ImageField(max_length=255, upload_to="profiles/", 

            null=True, blank=True, default="img/default_profile_image.png")

Then on the admin all I had to do was add sorl's AdminImageMixin on the UserProfileInline class, like this:

    from sorl.thumbnail.admin import AdminImageMixin

    class UserProfileInline(AdminImageMixin, admin.StackedInline):

        model = UserProfile

        verbose_name_plural = 'User Profile'

  And that way you get an image on the UserProfile Inline section on the admin for that user, now for the change_list.

For the change list I had to do a small callable function inside the admin.py file on the UserAdmin class, heres what I did, using sorl's get_thumbnail:

    from sorl.thumbnail import get_thumbnail

    class MyUserAdmin(UserAdmin):

        def image_thumbnail(self, obj):

            im = get_thumbnail(obj.get_profile().photo, '80x80', quality=99)

            return u"<img src='/site_media/%s' />" % im.url

        image_thumbnail.allow_tags = True

        list_display = ('image_thumbnail', 'username','email','first_name','last_name','date_joined',

        'last_login','is_staff', 'is_active',)

  And now I have a change list image of the user profile and also on the UserProfile Inline section.

Hope this works for everyone out there...
