how to use 2dicts in a for loop in Django template?

I have context as below :
context = {
'author': author,
'books':books,
}
Now I need to use author and books in One for loop like this :
{% for each in ***author & books*** %}
<tr>
<td>{{ each.author.name }}</td>
<td>{{ each.book.name }}</td>
<td>{{ each.book.pubishDate }}</td>
</tr>
{% endfor %}
How to make such a for loop in Django template?
Thanks all.

join 2 dictionaries into a list before sending it to the template(i.e in the view):
dicts = [dict1, dict2]
and try this:
{% for d in dicts %}
<tr>
<td> {{ d.x }} </td>
<td> {{ d.y }} </td>
</tr>
{% endfor %}

FlaskForm wtforms multiple input fields single submit

Using FlaskForm and SelectMultipleField, I'm creating a table of choices allowing for multiple selection to be ranked: 1, 2, 3, ... .
In order to place the choices in a grid pattern on a table, I made each row it's own instance of SelectMultipleField.
The submit button is only returning the values of the first instance of SelectMultipleField (dogs).
How can I get the submit button to return values in all instances of SelectMultipleField?
Here's the class in my forms module:
class LPRForm(FlaskForm):
party = ['Dogs', 'Cats', 'Rabbits', 'Birds']
dog = [('', 'D. Duke'), ('', 'R. Rusty'), \
('', 'T. Tucker'), ('', 'R. Roger')]
cat = [('', 'S. Shadow'), ('', 'M. Misty'), \
('', 'P. Patch'), ('', 'P. Paws')]
rabbit = [('', ''), ('', 'C. Clover'), ('', ''), ('', '')]
bird = [('', 'P. Pikachu'), ('', 'S. Starburst'), \
('', ''), ('', 'F. Flighty')]
vote_dog = SelectMultipleField('District', choices=dog,
option_widget=widgets.TextInput() )
vote_cat = SelectMultipleField('District', choices=cat,
option_widget=widgets.TextInput() )
vote_rabbit = SelectMultipleField('District', choices=rabbit,
option_widget=widgets.TextInput() )
vote_bird = SelectMultipleField('District', choices=bird,
option_widget=widgets.TextInput() )
submit = SubmitField('Cast Ballot')
Here's the relevant protion of the html file:
<table style="width:100%" align="center">
<tr>
<td> </td>
{% for vote in form.vote_dog %}
{% if vote.label != '': %}
<td>{{ vote(size="2") }}</td> <td>{{ vote.label }}</td>
{% endif %}
{% endfor %}
</tr>
<tr>
<td> </td>
{% for vote in form.vote_cat %}
{% if vote.label != '': %}
<td>{{ vote(size="2") }}</td> <td>{{ vote.label }}</td>
{% endif %}
{% endfor %}
</tr>
<tr>
<td> </td>
{% for vote in form.vote_rabbit %}
{% if vote.label != '': %}
<td>{{ vote(size="2") }}</td> <td>{{ vote.label }}</td>
{% endif %}
{% endfor %}
</tr>
<tr>
<td> </td>
{% for vote in form.vote_bird %}
{% if vote.label != '': %}
<td>{{ vote(size="2") }}</td> <td>{{ vote.label }}</td>
{% endif %}
{% endfor %}
</tr>
</table>
</td>
</tr>
{{ form.submit }}
And the view module:
#app.route('/lpr', methods=['GET', 'POST'])
def lpr():
form = LPRForm()
return render_template('lpr.html', title='Home', form=form)

I was able to get this working by using FormField. However, the documentation gives a default separator as -. Additionally, I explicitly identified separator='-', but only when I used . as a separator, when calling the class, did it work properly, ... even with separator='-'.

How can I show daily schedules of all users in Django?

I'm using Django to make a website for gym trainers.
what I want is a template for the daily schedules of all trainers like this
But, my page is
The problem is the 'td' of per trainer's tr repeats as many as the number of schedules the trainer has. I know the {% for sc in schedules %} is the problem. But, because schedules are the query set, I should use the for and while using for, I should check the right time to insert the schedule to the right tr, td position. How can I make the successful table to show the daily schedules of all users(trainers)?? Anybody will be very helpful to me.
Schedule.model
class Schedule(models.Model):
Trainer = models.ForeignKey(settings.AUTH_USER_MODEL,blank=True,null=True, related_name='schedule', on_delete=models.SET_NULL)
title = models.CharField(max_length=12,blank=True,)
start = models.DateTimeField(null=True, blank=True)
my views.py
def staff_daily_schedule_search(request):
all_schedules = Schedule.objects.all()
Fitness_list = User.objects.filter(groups__name='Fitness') # Fitness Trainers
search_date1 = request.GET.get('search_date','')
search_date= datetime.datetime.strptime(search_date1, '%Y-%m-%d') #%T = %H:%M:%S '%Y-%m-%d'
schedules= Schedule.objects.none()
for f in Fitness_list:
sc = f.schedule.filter(start__year=search_date.year).filter(start__month = search_date.month).filter(start__day = search_date.day)
print(sc)
schedules |= sc
context = {
'search_date' : search_date1 if search_date1 else datetime.date.today(),
'Fitness_list':Fitness_list,
'schedules' : schedules,
}
return render(request, 'management/staff_daily_schedule.html', context)
staff_daily_schedule.html
<form action="{% url 'management:staff_daily_schedule_search' %}" method="GET">
<span><input type="date" class="search_date my-control" name="search_date" value="{{ search_date }}" ></span>
<a id="today" class="btn btn-warning">오늘</a>
<button class="btn btn-info" value="검색" >검색</button>
</form>
<table class="table table-bordered">
<thead>
<tr>
<th></th>
<th>06:00 </th>
<th>07:00 ~ 07:50</th>
<th>08:00 ~ 08:50</th>
<th>09:00 ~ 09:50</th>
<th>10:00 ~ 10:50</th>
</tr>
</thead>
<tbody>
{% for trainer in Fitness_list %}
<tr>
<td>{{ trainer }} </td>
{% for sc in schedules %} <!-- because of this for, td repeats as many as the number of schedule per trainer has..-->
{% if sc.Trainer == trainer %}
{% if sc.start.hour == 21 %} <!--HOUR of 6:00 a.m = 21-->
<td>{{ sc }}</td>
{% else %}
<td ></td>
{% endif %}
{% if sc.start.hour == 22 %}
<td>{{ sc }}</td>
{% else %}
<td ></td>
{% endif %}
{% if sc.start.hour == 23 %}
<td>{{ sc }}</td>
{% else %}
<td ></td>
{% endif %}
{% if sc.start.hour == 0 %} <!-- 9 a.m. -->
<td>{{ sc }}</td>
{% else %}
<td></td>
{% endif %}
{% if sc.start.hour == 1 %}
<td>{{ sc }}</td>
{% else %}
<td></td>
{% endif %}
{% endif %}
{% endfor %}
</tr>
{% endfor %} <!-- tr repetition as trainers number-->
</tbody>
</table>
The problem

If you put the logic in your view instead of the template, it's easy to set up the table exactly like you want it.
[Edited to use an OrderedDict to preserve the order of trainers.]
views.py
def staff_daily_schedule_search(request):
Fitness_list = User.objects.filter(groups__name='Fitness') # Fitness Trainers
search_date1 = request.GET.get('search_date','')
search_date= datetime.datetime.strptime(search_date1, '%Y-%m-%d') #%T = %H:%M:%S '%Y-%m-%d'
trainer_dict = OrderedDict()
# Initialize each row of the table with the trainer's name and a blank schedule
for f in Fitness_list:
trainer_dict[str(f.id)] = {'name': f.get_full_name(), 'hour_21': '',
'hour_22': '', 'hour_23': '', 'hour_0': '', 'hour_1': ''}
schedules = Schedule.objects.filter(start__year=search_date.year).filter(start__month =
search_date.month).filter(start__day = search_date.day)
# Insert each schedule item into the appropriate table row and cell
for sc in schedules:
trainer_dict[str(sc.Trainer.id)]['hour_' + str(sc.start.hour)] = sc.title
context = {
'search_date' : search_date1 if search_date1 else datetime.date.today(),
'trainer_dict': trainer_dict
}
return render(request, 'management/staff_daily_schedule.html', context)
staff_daily_schedule.html
<form action="{% url 'management:staff_daily_schedule_search' %}" method="GET">
<span><input type="date" class="search_date my-control" name="search_date" value="{{ search_date }}" ></span>
<a id="today" class="btn btn-warning">오늘</a>
<button class="btn btn-info" value="검색" >검색</button>
</form>
<table class="table table-bordered">
<thead>
<tr>
<th></th>
<th>06:00 </th>
<th>07:00 ~ 07:50</th>
<th>08:00 ~ 08:50</th>
<th>09:00 ~ 09:50</th>
<th>10:00 ~ 10:50</th>
</tr>
</thead>
<tbody>
{% for trainer in trainer_dict %}
<tr>
<td>{{ trainer.name }}</td>
<td>{{ trainer.hour_21 }}</td>

How to iterate over a list in django templates? [duplicate]

This question already has answers here:
Using index from iterated list
(2 answers)
Closed 7 years ago.
I'm passing 4 lists of the same length and the length of the lists to my template. How do I iterate over the lists?
views.py
def allbooks(request):
ID = [1,2]
bookName = ["Python", "Java"]
author = ["idk", "who"]
copies = [3,7]
return render(request, 'allbooks.html',{'ID':ID,'bookName':bookName, 'author':author, 'copies':copies,'range':range(len(ID))})
allbooks.html
{% extends 'base.html' %}
{% block content %}
{% if user.is_authenticated %}
<div>
<h3>
List of books:
</h3>
<table class="table">
<thead>
<tr>
<th>ID</th>
<th>Book Name</th>
<th>Author</th>
<th>Number of copies</th>
</tr>
</thead>
<tbody>
{% for x in range %}
<tr>
<td>{{id[x]}}</td>
<td>{{bookName[x]}}</td>
<td>{{author[x]}}</td>
<td>{{copies[x]}}</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
{% else %}
<h3>You must login to continue.</h3>
{% endif %}
{% endblock %}
I've tried replacing the variable x with {% forloop.counter0 %} but to no avail. How can I fix this?

Zip all your lists to one list of tuples:
books= zip(ID, bookName, author, copies)
return render(request, 'allbooks.html',{ "books": books} )
Than loop over it in templates like:
{% for book in books %}
<tr>
<td>{{ book.0 }}</td>
<td>{{ book.1 }}</td>
<td>{{ book.2 }} </td>
<td>{{ book.3 }}</td>
</tr>
{% endfor %}
I suggest a better structure for your book info:
books = [
{ "id":1, "name": "Python", "author":"idk", "copies": 1},
{ "id":2, "name": "Java", "author":"idk2", "copies": 3}
]
than iterate through it:
{% for book in books %}
<tr>
<td>{{ book.id }}</td>
<td>{{ book.name }}</td>
<td>{{ book.author }} </td>
<td>{{ book.copies }}</td>
</tr>
{% endfor %}

flask wtform field data disappearingappend_entry

Please help - does flask/wtforms somehow treat the data property of a field differently after an append_entry call or am I just really doing this wrong?
I have a form that gets its data from a yaml file. On the initial GET request, the form populates showing the icons from the {% if ifc.poe.data %} as expected. If either button is hit to add a module or interface, the POST re-renders the page, but now ifc.poe.data is empty and thus no icons are rendered. If you comment out the if ifc.xxx.data portion and uncomment out the actual fields, the fields are rendered with the proper data every time. Is this something with how I'm building the form class or in how I'm handling the POST? What happened to the ifc.xxx.data?
Any help is appreciated, I'm pretty new at this.
