更改占位符 django cms 的背景颜色

Posted 2023-02-24

【中文标题】更改占位符 django cms 的背景颜色

【英文标题】：change background color of placeholder django cms

【发布时间】：2017-03-14 02:45:16

【问题描述】：

我希望用户能够更改占位符的颜色。

我尝试安装 djangocms-css-background。 我把这些步骤搁置了https://pypi.python.org/pypi/djangocms-css-background/1.0.4

起初我遇到错误：“找不到模块 djangocms-css-background”当我运行 python manage migrate.

不知何故，我修复了一个错误。但我坚持这个

djangocms-css-background.CssBackground.cmsplugin_ptr: (fields.E306) The name 'djangocms-css-background_cssbackground' is invalid related_name for field CssBackground.cmsplugin_ptr
    HINT: Related name must be a valid Python identifier or end with a '+'

我试过了

python manage.py makemigrations djangocms-css-background

我得到同样的错误

我在自述文件中看到了带 + 的语法。无论我把 + 放在哪里，我都会收到错误“invalid sintax”。

我正在使用 django 1.10，python 2.7

如果有人对此有任何建议或其他想法。 感谢您的帮助

【参考方案1】：

创建djangocms-css-background 包的人对应用程序的命名很糟糕，因为 python 不喜欢文件名包含连字符 (-)。他们应该将包中的***目录命名为djangocms_css_background。

存储库和 pypi 包可以包含连字符，它只是应用程序目录。

这就是你遇到问题的原因。

该软件包已折旧且不再维护，并且快速浏览会出现一些问题。

您可以分叉软件包，解决问题，然后安装您的软件包版本。

但是您到底想做什么，因为我对这个问题并不太清楚。如果您希望能够更改容器的背景颜色（就像这个应用程序允许的那样），重新创建非常简单。我只是不是 100% 你所说的“占位符的背景颜色”。

如果您提供更多信息，我可能会为您提供进一步的帮助。
