Question

我希望用户能够更改占位符的颜色。

我尝试安装djangocms-css-background。我拒绝了这些步骤https://pypi.python.org/pypi/djangocms-css-background/1.0.4

起初我有错误：“没有模块找到djangocms-css-background”当我运行python管理迁移时。

不知怎的，我修复了一个错误。但我坚持这一个

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

python manage.py makemigrations djangocms-css-background

我得到同样的错误

我在readme语法中看到了+。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

如果有人有任何建议或其他想法这样做。谢谢你的帮助

Answer 1

创建djangocms-css-background包的人对app的命名很差，因为python不喜欢包含连字符（ - ）的文件名。他们应该将包中的顶级目录命名为djangocms_css_background。

存储库和pypi包可以包含连字符，它只是app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，并且快速扫描有一些问题。

你可以分包，解决问题，然后安装你的软件包版本。

但是你究竟想做什么，因为我并没有过分清楚这个问题。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），那么重新创建它真的非常简单。我不是100％意味着占位符＆＃34;的背景颜色是什么意思。

如果您提供更多信息，我可以帮助您。
