我正在创建一个网站，并希望根据用户输入的蛋白质序列显示图像。我正在使用Genentech Pviz GitHub来帮助我创建图形，并从其网站复制了一个示例。当我在PyCharm中打开它时，它可以正常工作并显示正确的图像和图形，但是当我在views.py中将其作为模板打开时，它却不能。

我有显示结果的图像，但不知道如何提交。基本上应该有一个标题，下面有一个图形，但是只有标题和页脚才显示。基本上忽略了真正重要的图。
为什么在视图中调用网页时直接打开网页，而直接打开时为什么会更改？
就像我在另一个问题中所说的那样。我想为PVIZ创建标签，因为我找不到关于堆栈溢出的太多信息，因为它没有通用标签。 github链接是： https://github.com/Genentech/pviz
答案 0 :(得分：0)
看了大约3个小时，我发现了自己的错误。原来，静态css和JS文件的路径将转到错误的文件夹，该文件夹的名称与我认为也要使用的名称相同。
