如何在我的网站上看到翻译

Question

I am currently working on my website, which is a translator which you input a phrase and it gets translated into an invented language.

Here's the code of the translator function:

def translator(phrase):
    translation = ""
    for letter in phrase:
        if letter.lower() in "a":
            if letter.isupper:
                translation = translation + "U"
            else:
                translation = translation + "u"
        elif letter.lower() in "t":
            if letter.isupper:
                translation = translation + "A"
            else:
                translation = translation + "a"
        elif letter.lower() in "c":
            if letter.isupper:
                translation = translation + "G"
            else:
                translation = translation + "g"
        elif letter.lower() in "g":
            if letter.isupper:
                translation = translation + "C"
            else:
                translation = translation + "c"
    return translation

However, I am stuck in showing this funcion in my web, here's the code in views.py:

from .translate import translator

def translator_view(request):
    
    return render(request,'main/translator.html')

def translated_view(request):
    text = request.GET.get('text')
    print('text:', text)
    translate = translator
    dt = translator.detect(text)
    tr = translated.text
    context = {
        'translated': tr
    }
    return render(request, context, 'main/translated.html')

Here's the template where you introduce the text:

<form action="{% url 'translated' %}" method= "get">
    <div class="form-group">
        <center><h2 class = "display-3">TRANSLATE YOUR DNA CHAIN</h2></center>
        <br>
        <br>
        <textarea class="form-control" id="exampleFormControlTextarea1" rows="6"></textarea>
        <br>
        <button type='Submit' class= "btn btn-primary btn-lg btn-block">Translate</button>
    
    </div>   
</form>

Here's the template that should would show the translation.

{% extends "base.html"%}

{% block content%}

<div>
    <center><h2 class="display-4">DNA TRANSLATED SUCCESFULLY INTO</h2></center>
    <br>
    <br>
    <br>
    <h3>
        {{ translated }}
    </h3>
</div>   

{% endblock content%}

Why are you using GET request I think the best thing to do is to use a POST request.

def translated_view(request):
    text = request.POST['text']
    print('text:', text)
    translate = translator
    dt = translator.detect(text)
    tr = translated.text
    context = {
        'translated': tr
    }
    return render(request, context, 'main/translated.html')

<form action="{% url 'translated' %}" method="post">
    <div class="form-group">
        <center><h2 class = "display-3">TRANSLATE YOUR DNA CHAIN</h2></center>
        <br>
        <br>
        <textarea class="form-control" name="text" id="exampleFormControlTextarea1" rows="6"></textarea>
        <br>
        <button type='Submit' class= "btn btn-primary btn-lg btn-block">Translate</button>
    </div>   
</form>

But if you really want to use get request then you have an error. You haven't put a name attribute in the textarea so in your case it's:

<textarea class="form-control" name="text" id="exampleFormControlTextarea1" rows="6"></textarea>

and it your view its:

text = request.GET.get('text')
