Comments and Likes

1.  Create models comment и like;:


from django.db import models
from django.contrib.auth.models import User
from my_holiday.destination.models import Place

class Comment(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    place = models.ForeignKey(Place, on_delete=models.CASCADE)
    text = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return f"{self.user.username} - {self.place.name} - {self.created_at}"


class Like(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    place = models.ForeignKey(Place, on_delete=models.CASCADE, related_name='likes')

    def __str__(self):
        return f"{self.user.username} - {self.place.name}"


2. Update place_details.html

{% extends 'base.html' %}
{% block main_content %}
<section id="place-details">
    <h1>Place Details</h1>
    <div class="info-section">
        <div class="place-header">
            <img class="car-img" src="{{ place.image_url }}" alt="{{ place.location }}" />
            <h1>{{ place.category }}</h1>
            <p><span class="description">Name: {{ place.name }} </span></p>
            <p><span class="description">Description: {{ place.description }}</span></p>
            <p><span class="description">Rating: {{ place.rating }}</span></p>
        </div>

        <!-- Edit/Delete buttons -->
        <div class="buttons">
            <a href="#" class="edit-button">Edit</a>
            <a href="#" class="delete-button">Delete</a>
        </div>
    </div>

    <!-- Comments section -->
    <div class="comments-section">
        <h2>Comments</h2>
        <ul>
            {% for comment in place.comments.all %}
            <li>{{ comment.user.username }}: {{ comment.text }}</li>
            {% endfor %}
        </ul>

        <!-- Add comment form -->
        <form action="{% url 'add_comment' place.pk %}" method="post">
            {% csrf_token %}
            {{ comment_form.as_p }}
            <button type="submit">Add Comment</button>
        </form>
    </div>

    <!-- Likes section -->
    <div class="likes-section">
        <h2>Likes</h2>
        <p>{{ place.likes.count }} Likes</p>

        <!-- Like/unlike button -->
        {% if user.is_authenticated %}
        <form action="{% url 'add_like' place.pk %}" method="post">
            {% csrf_token %}
            <button type="submit">{% if user in place.likes.all %}Unlike{% else %}Like{% endif %}</button>
        </form>
        {% endif %}
    </div>
</section>
{% endblock %}


3. Create Views

# views.py

from django.shortcuts import redirect, get_object_or_404
from django.contrib.auth.decorators import login_required
from .forms import CommentForm, LikeForm
from .models import Comment, Like  # Importing the models

@login_required
def add_comment(request, place_id):
    place = get_object_or_404(Place, pk=place_id)
    if request.method == 'POST':
        form = CommentForm(request.POST)
        if form.is_valid():
            text = form.cleaned_data['text']
            Comment.objects.create(user=request.user, place=place, text=text)
    return redirect('details_place', pk=place_id)

@login_required
def add_like(request, place_id):
    place = get_object_or_404(Place, pk=place_id)
    like, created = Like.objects.get_or_create(user=request.user, place=place)
    if not created:
        like.delete()  # Unlike if already liked
    return redirect('details_place', pk=place_id)


4. Forms

# forms.py

from django import forms

class CommentForm(forms.Form):
    text = forms.CharField(widget=forms.Textarea)

class LikeForm(forms.Form):
    pass  # No fields needed, likes are handled via button click


5. Add in urls
