flask Blueprint template 蓝图模板

以下是错误的。

myapp/
    run.py
    admin/
        __init__.py
        views.py
        pages/
            index.html
    main/
        __init__.py
        views.py
        pages/
            index.html

_init_.py files are empty. admin/views.py content is:

from flask import Blueprint, render_template
admin = Blueprint('admin', __name__, template_folder='pages')

@admin.route('/')
def index():
    return render_template('index.html')

main/views.py is similar to admin/views.py:

from flask import Blueprint, render_template
main = Blueprint('main', __name__, template_folder='pages')

@main.route('/')
def index():
    return render_template('index.html')

run.py is:

from flask import Flask
from admin.views import admin
from main.views import main

app = Flask(__name__)
app.register_blueprint(admin, url_prefix='/admin')
app.register_blueprint(main, url_prefix='/main')

print app.url_map

app.run()

Now, if I access http://127.0.0.1:5000/admin/, it correctly displays admin/index.html. However, http://127.0.0.1:5000/main/ shows still admin/index.html instead of main/index.html. I checked app.url_map:

<Rule 'admin' (HEAD, OPTIONS, GET) -> admin.index,
<Rule 'main' (HEAD, OPTIONS, GET) -> main.index,

Also, I verified that index function in main/views.py is called as expected. If I rename main/index.html to something different then it works. So, without renaming, how can achieve that 1http://127.0.0.1:5000/main/1 shows main/index.html?
