尝试将用户输入的输出显示到同一个 html 屏幕上

Trying to display output from the user input onto the same html screen

我相信这并不难,我是 Django 的新手,非常感谢您的帮助。

我一直在尝试将两个输入('sentence' 变量和 'word' 变量)作为 CharFields。然后获取这两个输入并用它们创建一个新的输出。我可以在控制台上打印它,但不能在 html 页面上显示它。

谢谢。 这是我得到的。

--> form.html

    <div class="main">
        <div class="container">
            <div class="row">
                <form class="content" method="post">
                    {% csrf_token %}
                    {{ form }}
                    {% if output %}
                        <h3>{{ output }}</h3>
                    {% endif %}
                    <input type="submit" name="submit_cmd" value=Run />
                </form>
            </div>
        </div>
    </div>        

--> views.py

from django.shortcuts import render
from django.http import HttpResponse
from .forms import ContactForm
import subprocess as sp

import nltk
from nltk.corpus import wordnet
nltk.download('wordnet')

def contact(request):
    syn = set()
    output = ""
    form = ContactForm()

    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():

            sentence = form.cleaned_data['sentence']
            word = form.cleaned_data['word']

            for synonym in wordnet.synsets(word):
                for l in synonym.lemmas():
                    if l.name() != word:
                        syn.add(l.name().lower())

            for new_wrd in list(syn):
                print(sentence.replace(word, new_wrd))
                output += sentence.replace(word, new_wrd)


    return render(request, 'pk_app/form.html', {'form': form})

--> forms.py

from django import forms

class ContactForm(forms.Form):
    sentence = forms.CharField(required=True)
    word = forms.CharField(required=True)

您正在创建 output 变量,但从未将其附加到您 return 模板的上下文指令。

return render(request, 'pk_app/form.html', {'form': form, 'output': output})

另外:您确定它属于 HTML 表单元素中吗?
