Question

我刚刚开始学习Django，但遇到了一些障碍，希望有人可以提供帮助。

问题： 我的表单未显示在我的主要HTML模板（ingredior.html）中，但是该表单将显示在我的测试HTML模板（test.html）中，该模板只是带有{{form1}}标签的模板HTML文件。我正在手动更改views.py文件中的"return render(request, 'ingredior/ingredior.html', context)"，以测试两个不同的HTML模板。

ingredior.html test.html

问题： 更改后，为什么表单在test.html中而不在ingredior.html文件中起作用？

请记住，我正在将代码行"return render(request, 'ingredior/ingredior.html', context)"与"return render(request, 'ingredior/test.html', context)"交换以在两者之间进行测试。

代码---------

Forms.py

from django import forms

class UserInput(forms.Form):
    base_search_ingredient = forms.ChoiceField(choices=[('vegan', 'Vegan'), ('vegatarian', 'Vegatarian')])

views.py

from django.shortcuts import render
import requests
from .local_api_key import Key
from .forms import UserInput


def index (request):

    app_id = Key.app_id
    app_key = Key.app_key
    search_from = 0
    search_to = 100
    form1 = UserInput()
    test = []

    if request.POST.get('search'):
        test2 = request.POST.get('search')
        intolerance = test2
        url = requests.get(f"https://api.edamam.com/search?q={intolerance}&excluded=egg&excluded=beef&excluded=dairy&excluded=tomato&excluded=cherry%20tomatoes&excluded=rice&excluded=corn&excluded=soy&excluded=onion&from={search_from}&to={search_to}&health={intolerance}&app_id={app_id}&app_key={app_key}").json()
        recipe_length = (len(url['hits']))
    else:
        intolerance = 'vegan'
        url = requests.get(f"https://api.edamam.com/search?q={intolerance}&excluded=egg&excluded=beef&excluded=dairy&excluded=tomato&excluded=cherry%20tomatoes&excluded=rice&excluded=corn&excluded=soy&excluded=onion&from={search_from}&to={search_to}&health={intolerance}&app_id={app_id}&app_key={app_key}").json()
        recipe_length = (len(url['hits']))


    for urls in range(recipe_length):
        recipe_name = (url['hits'][urls]['recipe']['label'])
        recipe_url = (url['hits'][urls]['recipe']['url'])
        recipe_image = (url['hits'][urls]['recipe']['image'])
        recipe_healthLabels = (url['hits'][urls]['recipe']['healthLabels'])
        recipe_ingredients = (url['hits'][urls]['recipe']['ingredientLines'])
        test.append((recipe_name, recipe_url, recipe_image, recipe_healthLabels, recipe_ingredients))

    context = {'test': test, 'form1': form1}

    return render(request, 'ingredior/ingredior.html', context)

进一步调查： Inspection Image ingredior.html Inspection Image test.html

它们是相同的。
