eclipse中的tomcat 7项目(tomcat 7 project from eclipse)
我有一个在我的prod服务器Tomcat 7中运行良好的基础项目。
我将它导入到Eclipse中，创建了一个tomcat 7服务器来运行它并进行了一些开发。 一切工作正常在eclipse浏览器，但是当我导出的战争文件，并把它放在我的prod服务器上的
webapps文件夹中，我得到了以下错误：FAIL - Application at context path /art_current could not be started有关信息，我的Prod tomcat在Java7下，所以我在1.7中更改了我的项目构建路径和java编译器。
我试图在META-INF文件夹中创建一个context.xml文件：
<Context path="/art_current" />但仍然得到相同的错误
我注意到了一些事情，当我通过Eclipse导出项目时，项目结构发生了变化：
基本项目：
Eclipse导出的项目：
正如我们所见，有一些新的文件夹，特别是出现了一个META-INF文件夹，这是否正常？
也许我做错了什么，但我找不到什么
编辑
这里是我尝试从tomcat管理器启动我的应用程序时得到的日志：

base project that worked well in my prod server Tomcat 7.
I imported it in Eclipse, created a tomcat 7 server to run it and did some development. Everything work fine in eclipse browser but when i exported the war file and put it in
webappsfolder on my prod server i got the following error :FAIL - Application at context path /art_current could not be startedFor information, my Prod tomcat is under Java7 so i changed my project build path and java compiler in 1.7.
I tried to create a context.xml file in META-INF folder:
<Context path="/art_current" />but still get the same error
I have noticed something, when i export my project by Eclipse, the project structure is altered :
Basic Project :
Exported project from Eclipse :
As we can see, there is some new folders and in particular a META-INF folder appeared, is it normal ?
Maybe i am doing something wrong but i can't find what
EDIT
here are the log i get when i try to start my app from tomcat manager :

首先，将
uuid字段添加到User模型。 创建迁移。然后，创建数据迁移并添加RunPython操作以调用将数据从旧模型复制到新模型的函数。 就像是：
def copy_uuid(apps, schema_editor): User = apps.get_model("myapp", "User") # loop, or... User.objects.update(uuid=F("userprofile__uuid")) class Migration(migrations.Migration): dependencies = [] operations = [ migrations.RunPython(copy_uuid), ]迁移并确保一切正常后，您可以在另一次迁移中删除
UserProfile模型。First, add the
uuidfield to theUsermodel. Create a migration.Then, create a data migration and add a RunPython operation to call a function that copies the data from the old to the new models. Something like:
def copy_uuid(apps, schema_editor): User = apps.get_model("myapp", "User") # loop, or... User.objects.update(uuid=F("userprofile__uuid")) class Migration(migrations.Migration): dependencies = [] operations = [ migrations.RunPython(copy_uuid), ]Once you've migrated and are sure that everything worked, you can delete the
UserProfilemodel in another migration.

如果你很乐意任意选择其中的一个副本，我认为以下几点可能会起作用。 也许不是最有效，但很简单，我想你只需要运行一次。 请确认这一切都适用于某些测试数据，以防万一我做了一些愚蠢的事情，因为您将要删除一堆数据。 首先我们找到形成重复的对象组。 对于每个组，（任意）选择一个我们将要保留的“主”。 我们选择的方法是选择pk最低的方法 master_pks = MyModel.objects.values('A', 'B', 'C' ).annotate(Min('pk'), count=Count('pk') ...

为了独特性检查的目的，Django并没有将NULL视为NULL，因为售票＃9039已修复，请参阅： http://code.djangoproject.com/ticket/9039 这里的问题是表单CharField的归一化“空白”值是空字符串，而不是无。 所以如果你把这个字段留空，你会得到一个空的字符串，而不是NULL，存储在数据库中。 在Django和数据库规则下，空字符串等于唯一性检查的空字符串。 您可以通过为Foo提供自己的自定义模型窗体来强制管理界面为空字符串存储NULL，并使用clean_ba ...

如何Django模型(How to Django models)[2021-11-21]
如何添加索引（在某些字段上）？ 我可以通过Django模型层完成吗？ 您可以。 看看Field.db_index选项。 如果我想将一些旧数据迁移到这些新的数据库表/模型中，我是否必须自己编写一些脚本，或者Django是否为模式映射工具提供了模式？ Django没有内置工具来进行数据迁移。 要迁移现有数据，您必须编写自定义脚本。 这可能是使用外部迁移工具（如南，见下文），但我还没有尝试过。 最后，如果我需要更改现有Django模型的模式，那么最简单的方法是什么？ 我知道这取决于我的架构但是它就像创建一个新列并 ... -

现在，您似乎正在尝试使用CharField模拟UUID（通用唯一标识符）。 虽然这种方法可能不会引起太多问题（毕竟它确实提供了（26 + 26 + 10）** 21种可能的组合），但这是一种非常天真的方法。 为什么不使用Django的原生UUIDField ？ 这是一个例子： class Organization(models.Model): name = models.CharField(max_length=255) key = models.UUIDField(default=uuid ...
