Flask错误:“不允许使用方法所请求的URL不允许使用该方法" [英] Flask Error: "Method Not Allowed The method is not allowed for the requested URL"
问题描述
每当我尝试将数据提交到Flask表单时，都会出现以下错误:
I'm getting the following error whenever I try to submit data to my Flask form:
Method Not Allowed The method is not allowed for the requested URL.
我认为问题出在我正在执行的return redirect(url_for('database'))中.我也尝试过return render_template('database.html).表单项提交到数据库后，我正在尝试调用数据库页面.
I think the issue is in the return redirect(url_for('database')) I'm doing. I've also tried return render_template('database.html) too. I'm trying to call the database page once form entries have been submitted to the database.
我的代码的相关部分如下:
Relevant parts of my code are as follows:
@app.route('/entry', methods=['GET', 'POST'])
def entry_page():
if request.method == 'POST':
date = request.form['date']
title = request.form['blog_title']
post = request.form['blog_main']
post_entry = models.BlogPost(date = date, title = title, post = post)
db.session.add(post_entry)
db.session.commit()
return redirect(url_for('database'))
else:
return render_template('entry.html')
@app.route('/database')
def database():
query = []
for i in session.query(models.BlogPost):
query.append((i.title, i.post, i.date))
return render_template('database.html', query = query)
entry.html是...
entry.html is...
THIS IS THE BLOG ENTRY PAGE
blog:
<html>
<form action='/database' method = "post">
date<input name = "date" type = "text" class="text">
title<input name = "blog_title" type = "text" class="text">
main<input name = "blog_main" type = "text" class="text">
<input type = "submit">
</form>
</html>
和database.html ...
and database.html...
THIS IS THE QUERY:
{{query}}
推荐答案
这里发生的是数据库路由不接受任何url方法.
What is happening here is that database route does not accept any url methods.
我会尝试将url方法放在应用程序路由中，就像在entry_page函数中一样:
I would try putting the url methods in the app route just like you have in the entry_page function:
@app.route('/entry', methods=['GET', 'POST'])
def entry_page():
if request.method == 'POST':
date = request.form['date']
title = request.form['blog_title']
post = request.form['blog_main']
post_entry = models.BlogPost(date = date, title = title, post = post)
db.session.add(post_entry)
db.session.commit()
return redirect(url_for('database'))
else:
return render_template('entry.html')
@app.route('/database', methods=['GET', 'POST'])
def database():
query = []
for i in session.query(models.BlogPost):
query.append((i.title, i.post, i.date))
return render_template('database.html', query = query)
