Question

我尝试使用python在Django中添加搜索字段。以下是我使用过的代码。

# admin.py file

from django.db import models
from blog.models import Blog
from django.contrib import admin
admin.site.register(Blog)

class Blog(models.Model):
    title = models.CharField(max_length=60)
    body = models.TextField()
    created = models.DateTimeField("Date Created")
    updated = models.DateTimeField("Date Updated")
    def __unicode__(self):
        return self.title

class Comment(models.Model):
    body = models.TextField()
    author = models.CharField(max_length=60)
    created = models.DateTimeField("Date Created")
    updated = models.DateTimeField("Date Updated")
    post = models.ForeignKey(Blog)
    def __unicode__(self):
        return self.body

class CommentInline(admin.TabularInline):
    model = Comment


class BlogAdmin(admin.ModelAdmin):
    list_display = ('title','created', 'updated')
    search_fields = ['title','body']
    list_filter = ('Date Created','Date Updated')
    inlines = [CommentInline]

class CommentAdmin(admin.ModelAdmin):
    list_display = ('post','author','body_first_60','created','updated')
    list_filter = ('Date Created','Date Updated')

我尝试使用以下代码为标题和正文添加search_fields。

class BlogAdmin(admin.ModelAdmin):
    . . .
    search_fields = ('title','body')
    . . .

当我运行时，我看不到任何搜索框。这是为什么？我想要你的帮助。我只是个初学者。谢谢！

Answer 1

搜索字段应该是列表，而不是元组。

class BlogAdmin(admin.ModelAdmin):
    . . .
    search_fields = ['title','body']
    . . .

然后确保将此管理对象与模型相关联。

admin.site.register(Blog, BlogAdmin)

修改

上面很难说，但你应该考虑从models.py导入模型，而不是在admin.py文件中重新定义它们。再次，看起来这就是你正在做的事情。

admin.py：

from django.db import models from blog.models import Blog from django.contrib import admin class CommentInline(admin.TabularInline): model = Comment class BlogAdmin(admin.ModelAdmin): list_display = ('title','created','updated',) search_fields = ['title','body',] list_filter = ('Date Created','Date Updated',) inlines = [CommentInline,] class CommentAdmin(admin.ModelAdmin): list_display = ('post','author','body_first_60','created','updated',) list_filter = ('Date Created','Date Updated',) admin.site.register(Blog, BlogAdmin)

models.py

from django.db import models class Blog(models.Model): title = models.CharField(max_length=60) body = models.TextField() created = models.DateTimeField("Date Created") updated = models.DateTimeField("Date Updated") def __unicode__(self): return self.title class Comment(models.Model): body = models.TextField() author = models.CharField(max_length=60) created = models.DateTimeField("Date Created") updated = models.DateTimeField("Date Updated") post = models.ForeignKey(Blog) def __unicode__(self): return self.body

您应该在网站底部而不是在顶部注册您的网站请尝试页面底部的admin.site.register（博客，BlogAdmin）。
