xlsxwriter 到 http 响应（下载文件）但在 django 中带有用户数据（表单）

Question

我卡住了，我想在页面上创建模板的用户输入数据将创建一个模板。这是我到目前为止得到的，但它不会工作，我已经尝试过在线示例，但这些通常不会从用户那里获取数据来创建模板。

这是views.py

from django.http import HttpResponse
from django.shortcuts import render
import xlsxwriter
from xlsxwriter import workbook
from django.forms import Form, CharField, ChoiceField, IntegerField
from django.core.validators import MaxValueValidator, MinValueValidator

def home(request):
    return render(request, 'my_app/home.html')

class TemplateForm(Form):
    doc_name = CharField(label='Document name')
    sheetnames = CharField(label='Sheetnames')
    choices = []
    for year in range (1900, 2050):
        choices.append( (year, year) )
    year1 = ChoiceField(label='Starting Year', initial=2021, choices=choices)
    year2 = ChoiceField(label='Ending Year', initial=2022, choices=choices)    
    row_names = CharField(label='Column names')

def create_template(request):
    if request.method == 'GET':
        form = TemplateForm()
        return render(request, 'my_app/create_template.html', {'form':form})
    else:
        form = TemplateForm(request.POST)

def create_form(doc_name, sheetnames, years, row_names):
    workbook = xlsxwriter.Workbook(doc_name + '_template.xlsx')
    worksheet_introduction = workbook.add_worksheet( "introduction" )
    for i in sheetnames:
        worksheet_data = workbook.add_worksheet(i)
        worksheet_data.write_row(0, 1, years)
        worksheet_data.write_column(1, 0, row_names)
    workbook.close()
    return workbook

这是my_app/templates/my_app/create_template.html

{% extends "my_app/base.html" %}
{% block content %}

<form action="create_template" method="GET">
  {% csrf_token %}
  <h1>Create your template</h1>
  <div class="item">
    <table>
      {{ form.as_table }}
    </table>
  </div>
  <div class="btn-block">
    <input type="button" type="submit" value="Create and Download!"/>
  </div>
</form>
{% endblock content %}

这是my_app/urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='my-home'),
    path('create-template/', views.create_template, name='my-create-template'),
]

Answer 1

我猜函数 create_template 重复了？

`def create_template(request):
    return render(request, 'my_app/create_template.html')`

`def create_template(request):
    if request.method == 'GET':
        form = TemplateForm()
        return render(request, 'my_app/create_template.html', {'form':form})
    else:
        form = TemplateForm(request.POST)`

第一个不包含 TemplateForm()。它总是这样调用：路径（'create-template/'，views.create_template，名称='my-create-template'） .尝试删除第一个。
