不返回烧瓶形式

Question

我已经阅读了许多讨论并尝试了各种选项，即 request.form.get()、request.args.get()。我没有从表单中得到任何传递？？

<div class="modal-body"> <h1> Affiliated Programmes </h1>
    <form id="grant_edit" action="" method="POST">                      
        <input type="hidden" id="popup_grant_id" name="grant_id"/>
        <div class="checkbox" id="programmes_container">
        </div><br/><br/>                    
        <button name="grant_submit" type="submit" value="programmes">              
                <span class="glyphicon glyphicon-save"></span> Update 
        </button>                           
    </form>
</div>

按钮名称是“grant_submit” “GET”返回ID，“POST”不响应。

@app.route('/searchgrantprogs', methods=['POST', 'GET'])
# called by publication allocation using ajax
@login_required
def searchgrantprogs():

    grant_id = 0

    if request.method == 'GET':
        sql_grantprogs = """SELECT grant_id, programme_id 
                    FROM grants_programmes WHERE grant_id=:a;
                    """
        grantid = request.args.get('grant_id')
        print(grantid)
        r_grantprogs = list(conn.execute(text(sql_grantprogs), a=grant_id))
        return json.dumps([dict(r) for r in r_grantprogs])


    if request.method == 'POST':
        for gr in request.form.values():
            #form=grant_submit()
            grant_id = request.form.get('grantid')
            ##clustid=request.form['grant_submit']
            flash(request.form.get('grant_submit'))


    #return redirect(url_for('searchgrants'),)
    return render_template('search_grants.html', grant_id=grantid)

错误信息：

我无法获取表单详细信息？？

我将不胜感激。

Answer 1

你有grantid而不是grant_id

开关

grant_id = request.form.get('grantid')

到：

grantid = request.form.get('grant_id')
