django base_fields
时间: 2023-05-22 18:01:15 浏览: 197
Django 的 base_fields 是一个字典,它包含了所有表单字段的定义。这些字段可以是内置的字段,也可以是自定义的字段。在 Django 中,表单是通过继承 forms.Form 类来创建的,而 base_fields 就是这个类中的一个属性。通过修改 base_fields,我们可以自定义表单的字段。

这个错误提示是在 Django 管理界面(admin)操作 `material_scrap.models.MaterialScrapHead` 这个模型时出现的,具体是在 `save_model` 方法中,尝试获取 `request.POST['materialscrapdetail_set-0-reason']` 时出现了问题。
根据错误提示,可以看到是 `MaterialScrapDetail.serialNum` 属性应该是 `MaterialScrapHead` 类型的实例,但是却传入了 `class 'material_scrap.models.MaterialScrapHead'` 这个类对象,所以出现了错误。
需要检查你的代码,确认 `MaterialScrapDetail.serialNum` 属性是否正确设置,并且在获取 `request.POST` 参数时是否正确,建议先在代码中加入一些调试信息,逐步排查问题。
django-ueditor如何使用
Django-ueditor是一个用于将百度富文本编辑器(UEditor)集成到Django Web应用中的第三方库。以下是基本步骤来安装和使用它:
1. **安装**:
使用pip安装:
```
pip install django-ueditor
```
2. **配置**:
- 在`settings.py`中添加到INSTALLED_APPS列表中,并设置静态文件目录路径:
```python
INSTALLED_APPS = [..., 'django_ueditor']
STATIC_URL = '/static/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]
```
- 在`settings.py`中配置ueditor的配置项,例如服务器地址、文件保存路径等。
3. **模型字段**:
在需要富文本编辑的模型中,添加`ckeditor_uploader`字段:
```python
from django.db import models
from django_ckeditor_uploads.fields import RichTextUploadingField
class MyModel(models.Model):
content = RichTextUploadingField()
```
4. **视图和模板**:
- 在视图函数中,实例化Ueditor对象并返回响应:
```python
from django.shortcuts import render
from django.core.files.storage import FileSystemStorage
from django_ueditor.widgets import UEditorWidget
def my_view(request):
# 创建文件存储对象
storage = FileSystemStorage(location='media/ueditor/')
# 初始化ueditor widget
ueditor_widget = UEditorWidget(storage=storage)
context = {'content': ueditor_widget}
return render(request, 'my_template.html', context)
```
5. **模板**:
在HTML模板中,引入ueditor.js和样式文件,然后使用`ckeditor`标签插入富文本编辑区域:
```html
{% load static %}
<script type="text/javascript" src="{% static 'ueditor/ueditor.config.js' %}"></script>
<script type="text/javascript" src="{% static 'ueditor/ueditor.all.min.js' %}"></script>
<script id="id_content" name="content">
<!-- 这里由前端框架填充 -->
</script>
<!-- ...其他内容... -->
<textarea id="id_my_model_content" rows="10" cols="80">{% csrf_token %}{{ content|safe }}</textarea>
```
6. **上传处理**:
需要创建一个处理文件上传的URL,通常与`MEDIA_URL`关联,并在ueditor配置中设置。
