Comment is not displaying in django after submission

I have tried to submit a comment from app rather than django admin. Comment is not displaying when submitted from my created app. But it is displaying when I add a comment from django admin app. May be I am doing something wrong in views.py file. Can anyone help me on this? Thank you.
views.py:
#login_required
def book_review(request,id):
book = get_object_or_404(Bookslist, id=id)
comment=Comment.objects.all().filter(post_id=id)

form = CommentForm(request.POST)
if form.is_valid():
post = form.save(commit=False)
post.user_id = request.user
post.message= comment
post.save()
return redirect('book_review', id=id)
else:
form=CommentForm()
return render(request, "books/book_review.html", {'book':book, 'comment':comment, 'form': form})

You need to add the post_id to the newly created comment.
Like so:
post.post_id = id
Also make sure you are using the correct naming for your variables i believe post should be comment in this scenario based on the form being of CommentForm: model = Comment
This replacement would make for sense for the code:
if request.method == 'POST':
form = CommentForm(request.POST)
if form.is_valid():
comment = form.save(commit=False)
comment.user_id = request.user
comment.message= comment
comment.post_id = id
comment.save()

Django search / filter across multiple models

In my Django website, I'm trying to create a search bar on my homepage that returns results that are stored in two different models(Articles, Jobs)
Currently, I get an empty result set when I search using this code:
In models.py,
class Articles(models.Model):
objects = None
news_title = models.CharField(db_column="title", max_length=400)
news_url = models.URLField(db_column="link", max_length=400)
image_link = models.CharField(db_column="image", max_length=400)
published_date = models.CharField(db_column="published_date", max_length=400)
class Meta:
managed = False
db_table = "articles"
def __str__(self):
return self.news_title
class Jobs(models.Model):
objects = None
company = models.CharField(db_column='company', max_length=100)
job_title = models.CharField(db_column='job_title', max_length=300)
experience = models.CharField(db_column='experience', max_length=300)
edu_level = models.CharField(db_column='edu_level', max_length=50)
class Meta:
managed = False
db_table = "job_list"
def __str__(self):
return self.job_title
In views.py,
class SearchView(ListView):
template_name = 'blog/search_results.html'
def get_queryset(self):
request = self.request
query = request.GET.get('q', '')
articles_results = Articles.objects.filter(Q(news_title__icontains=query))
jobs_results = Jobs.objects.filter(Q(job_title__icontains=query))
context={
'articles':articles_results,
'jobs':jobs_results,
}
return render(request, 'blog/search_results.html', context)
In main_view.html, I'm using this code for creating a search bar:
<form action="{%url 'search_results' %}" method="get" values="{{request.GET.q}}" class="search-jobs-form">
<div class="row mb-5">
<input name="q" type="text" values="{{request.GET.q}}" placeholder="search">
</div>
<button type="submit">Search</button>
</form>
And in search_results.html,
{% block content %}
{% for job in jobs %}
<h5>{{job.job_title}}</h5>
<p>{{job.company}}</p>
{% endfor %}
{% for article in articles %}
<h5>{{article.news_title}}</h5>
<p>{{article.published_date}}</p>
{% endfor %}
{% endblock %}

I ended up not using class SearchView(ListView) in views.py and made it work
Here's the code that I used
#index.html Search Bar
<form method="get" class="search-jobs-form" action="{% url 'main_search'%}">
{% csrf_token %}
<input type="text" placeholder="Job title, Company..." name="search_query">
<button type="submit" class="btn btn-info btn-lg btn-block text-white btn-search">Search Job</button>
</form>
In views,
#views.py
def main_search(request):
q = request.GET['search_query']
articles = Articles.objects.filter(news_title__icontains=q)
jobs = Jobs.objects.filter(Q(job_title__icontains=q) | Q(company__icontains=q))
return render(request, "blog/main_search.html", {'articles':articles, 'jobs':jobs, 'page_name':'Search Results', 'q':q})

Get multiple data from checkbox using "request.POST.get"

I tried to get multiple data from the checkbox using method below in my views.py:
if (((request.POST.get('data_choice ')) == ('Salary')) and ((request.POST.get('data_choice ')) and ((request.POST.get('data_choice ')) == ('Overtime')) ):
But the problem is the "and" condition is not working but if i use "or" condition it's work. May I know what's the problem with my code ? Is the request.POST.get can only get 1 data ?
choices.py
class DataChoices(models.TextChoices):
salary = 'Salary',_('Salary')
bonus = 'Bonus',_('Bonus')
allowance= 'Allowance',_('Allowance')
overtime= 'Overtime',_('Overtime')
models.py

Data_choices = Data_choices
data_choices = models.CharField(max_length=40,choices=Data_choices.choices,blank = True, null= True)
forms.py
class dataForm(forms.ModelForm):
datachoice = DataChoices
data_choice = forms.MultipleChoiceField(label=False,choices=datachoice .choices, required=True,widget=forms.CheckboxSelectMultiple(
attrs= {

}))
class Meta:
model = Data
fields = ('__all__')

</div>
</div>
</fieldset>
</form>
views.py
if form.is_valid:

}
if (((request.POST.get('data_choice ')) == ('Salary')) and ((request.POST.get('data_choice ')) == ('Bonus')) ):
request.session['decision_data'] = data
return redirect ('printformA')
else:
messages.error(request, f'Error in creating Form')
return render(request, 'selectdata.html',context)

use QueryDict.getlist(key, default=None)
Usage:
data_choice = request.POST.getlist('data_choice')

How to compare a database foreign key value with form foreign key value in Django?

I have a Django project and I encountered with a problem of comparing a database foreign key attribute with form foreign key attribute. My project files are below :
My Model.py File:
class Teacher(models.Model):
Name = models.CharField(max_length=100)
Designation = models.CharField(max_length=100,choices=DESIGNATION)
Department = models.CharField(max_length=100,choices=T_Dept)
Address = models.CharField(max_length=100)
def __str__(self):
return self.Name + ", " + self.Designation + ", " + "("+self.Department +"), "+ self.Address
class Moderation(models.Model):
year = models.CharField(max_length=100,choices=T_Year)
semester = models.CharField(max_length=100,choices=T_Semester)
examtype = models.CharField(max_length=30,choices=EXAMTYPE)
examyear = models.CharField(max_length=30,choices=EXAMYEAR)
NamAdd = models.ForeignKey(Teacher, on_delete=models.CASCADE)
position = models.CharField(max_length=100,choices=POSITON)

How to compare obj.NamAdd.Name == NamAdd in view File? Please help me by providing any hint.
Basically, I want to save a unique Moderation object into database How doing this? Has any alternative way?
Thanks advance.

Whats wrong with obj.NamAdd == NamAdd ?
Many.
The primary issue for the comparison failure is that NamAdd is an integer(Teacher object id) where obj.NamAdd is a model object.
So, on this regard, it should be obj.NamAdd.id == NamAdd
Don't do this please. Not that way. You are bypassing input validation.
It could be obj.NamAdd == modForm.cleaned_data['NamAdd']
Since you want unique Moderation,
add this to the model:
class Meta:
unique_together = (('year', 'semester', 'examtype', 'examyear', 'NamAdd', 'position'))
so that it now looks like
class Moderation(models.Model):
year = models.CharField(max_length=100, choices=[])
semester = models.CharField(max_length=100, choices=[])
examtype = models.CharField(max_length=30, choices=[])
examyear = models.CharField(max_length=30, choices=[])
NamAdd = models.ForeignKey(Teacher, on_delete=models.CASCADE)
position = models.CharField(max_length=100, choices=[])
def __str__(self):
return unicode(self.NamAdd)
class Meta:
unique_together = (('year', 'semester', 'examtype', 'examyear', 'NamAdd', 'position'))
(remember makemigrations and migrate)
**note I used empty list for choices, adjust for your case.
now in the view, use this for checking moderation existence:
moderation_exists = Moderation.objects.filter(year=modForm.cleaned_data['year'], semester=modForm.cleaned_data['semester'],examtype=modForm.cleaned_data['examtype'], examyear=modForm.cleaned_data['examyear'], NamAdd=modForm.cleaned_data['NamAdd'], position=modForm.cleaned_data['position']).exists()
if moderation_exists:
context = {'fMod': fMod, 'modForm': modForm,
'msg': "<span style='color:red;'><h3>Already Inserted!</h3> Last entry : </span>"}
flag = False

SQLAlchemy with Flask does not commit

When I submit my form from webpage, I am not able to commit. Flashing data I need, I see they're there and correct, but something fails when committing. I am sure I am making a mistake somewhere because mostly commit are working except two. This is one of the two that is not working.
Models:
class Feedback(db.Model):
__tablename__ = 'feedback'
id = db.Column(db.Integer, primary_key = True)
rate = db.Column(db.Integer)
comment = db.Column(db.Text())
sender_id = db.Column(db.Integer)
receiver_id = db.Column(db.Integer)
Forms:
class LeaveFeedbackForm(Form):
rate = IntegerField('Rate', validators = [DataRequired(),
NumberRange(min = 1, max = 5, message = 'Rates admitted are only 1,2,3,4,5')])
comment = TextAreaField('Comment', validators = [DataRequired()])
submit = SubmitField('Submit')
Views:
#app.route('/leave_feedback/<sender>/<receiver>', methods = ['GET', 'POST'])
def leave_feedback(receiver, sender):
form = LeaveFeedbackForm()
rec = int(receiver)
sen = int(sender)
if form.validate_on_submit():
feedback = Feedback( rate = form.rate.data,
comment = form.comment.data,
receiver_id = rec,
sender_id = sen
)
db.session.add(feedback)
db.session.commit()
flash('Feedback Left Correctly.')
return redirect(url_for('index'))
flash(form.rate.data)
flash(form.comment.data)
flash(rec)
flash(sen)
return render_template('leave_feedback.html', receiver_id = receiver, sender_id = sender, form = form)
html:
{% block content %}
<div class="row">
<div class="large-6 columns">
<h1>Leave Feedback</h1>
</div>
</div>
<form action="" method="post" name="leavefeedback">
<div class="row">
<div class="large-6 columns">
<label>Rate
{{ form.rate }}
</label>
</div>
</div>
<div class="row">
<div class="large-6 columns">
<label>Comment
{{ form.comment }}
</label>
</div>
</div>
<div class="row">
<div class="large-6 columns">
<input class="button radius" type="submit" value="Leave Feedback">
</div>
</div>
</form>
{% endblock %}

You should add an else statement:
if form.validate_on_submit():
...
else:
for error in form.errors.itervalues():
flash(error[0])
Then you will get an error message from form.

I figured out my mistake, I simply forgot in my form:
{{ form.hidden_tag() }}
