I don't know what is the problem and I've been stuck here for hours. There maybe duplicate questions but none of them could get me out of this.
I am using an if condition in the inner loop to check if the attribute of inner is equal to the outer loop but if condition is never true even the data is same.
I've printed the data individually, both attributes print the data mean data is correct. But when I use if condition it goes to else
Data
Here's the data I'm working with:
activityy.activity_name = [Table Tennis,Swimming Pool, Football ]
slot.activity = [Table Tennis,Table Tennis,Table Tennis,Table Tennis,Swimming Pool, Football]
activities.html
{% for activityy in all_activities%}
<div style="margin-left: 450px; padding: 15px; border-radius: 5px; background-color: #dfdfdf;height: 150px; width: 800px; margin-top: 20px; text-align: center">
{% for slot in all_slots %}
{% if slot.activity == activityy.activity_name %}
<div style="background-color: #3a589a; padding: 15px; width: 120px; height: 120px; float: left; border-radius: 5px;">
<span style="color: #f1f1f1; font-size: 20px;"> {{ activityy.activity_name}}</span><br>
</div>
{% else %}
<div style="background-color: #589a; padding: 15px; width: 120px; height: 120px; float: left; border-radius: 5px;">
<span style="color: #f1f1f1; font-size: 20px;"> {{ slot.activity}}</span><br>
</div>
{% endif %}
{% endfor %}
</div>
{% endfor %}
Views.py
def activities(request):
if request.user.is_authenticated:
template = loader.get_template('sklc/activities.html')
slots = []
now = datetime.datetime.now()
datee = now.strftime("%Y-%m-%d")
if request.method == 'POST':
dat = request.POST['date']
if dat:
datee = dat
print("dateesss: " , datee)
activitiess = Activities.objects.all();
for activityy in activitiess:
slot = ActivitySlots.objects.filter(dates=datee).filter(activity__activity_name=activityy.activity_name)
for slott in slot:
slots.append(slott)
context = {
'all_activities': activitiess,
'all_slots': slots
}
return HttpResponse(template.render(context, request))
else:
messages.error(request, "Please Login First")
return redirect("/login")
models.py
class Activities(models.Model):
activity_name = models.CharField(max_length=50)
def __str__(self):
return self.activity_name
class ActivitySlots(models.Model):
dates = models.DateField()
available = models.BooleanField()
activity = models.ForeignKey(Activities)
time = models.CharField(max_length=50)
def __str__(self):
return self.time
I solved it by using
{% if slot.activity == activityy %}
Butt still don't know why it was not working with activityy.activity_name because activityy and activityy_activity_name are printing the same thing.

SO here whenever the user submit the incoming QC and Manufacturing forms. The Quantity entered by the user in both the form or single form I want to subtract the Quantity of the Material data.
Note: The Quantity should be subtracted based on the manufacturing_PN.
It should look like below logic:
if Material.manufacturing_PN == Manufacturing.manufacturing_PN || Material.manufacturing_PN == Incoming_QC.manufacturing_PN
Material.manufacturing_PN = Material.manufacturing_PN - Incoming_QC.manufacturing_PN - Manufacturing.manufacturing_PN
It would be very helpful if someone help me out in this. Thanks in advance
im trying to create a django page for update a dta inside database, i made this before in other projects and aways worked, but in my project it returns this error: django.urls.exceptions.NoReverseMatch: Reverse for 'update' with arguments '('',)' not found. 1 pattern(s) tried: ['update/(?P[0-9]+)$']
i reviewed my code a thousand times and i can't see nothing wrong, even if comparing with the other projects.
Obs.: please ignore the css part of my template, i'm not used to write the css inside the html, but as it's just a test i don't create a external file.

transacao is not a variable in your template, you use list as a variable for a Transacao object, therefore you should use {% url 'update' list.id %} and {% url 'delete' list.id %}:
{% for list in lists %}
<tr>
<td>{{ list.desc }}</td><td>{{ list.date }}</td>
<td>{{ list.value }}</td><td>{{ list.categ }}</td>
<td><form action="{% url 'update' list.id %}">
<button type="submit"><b>Editar</b></button>
</form></td>
<td><form action="{% url 'delete' list.id %}">
<button type="submit"><b>Excluir</b></button>
</form></td>
</tr>
{%endfor%}
That being said, since your lists is not a collection of lists - it is a QuerySet of Transacaos - it might be better to rename lists to transacaos and use transacao as "enumerator".
I had a problem with this jinja2.exception and I was totally confused why. I wanted to post data to my .html, which I got from an API.
#app.route("/playerstats", methods = ["GET"])
def statsget():
return render_template("stats.html")
#app.route("/playerstats", methods = ["POST"])
def statspost():
player_uri = "https://www.balldontlie.io/api/v1/players?search={}%20{}"
playerinput = request.form["nm"]
player_split = playerinput.split()
vn = player_split[0]
nn = player_split[1]
r = requests.get(player_uri.format(vn, nn)).json()
data = {
"player_id": r["data"][0]["id"],
"player_first_name": r["data"][0]["first_name"]
}
return render_template("stats.html", data=data)
<button type="button" class="btn btn-outline-secondary" style="height: 40px; width: 450px; margin-top: 5px; margin-bottom: 5px; border-width: 1px; border-color:lightgrey; text-align: start;">
{{data.player_first_name}} {{data.player_id}}
</button>
Running the webpage put out this exception: jinja2.exceptions.UndefinedError 'data' is undefined
My solution was to put the data I get from the api into an array and run a for-loop inside the html to give out all data:
inside main.py:
#app.route("/playerstats", methods = ["GET"])
def pstatsget():
return render_template("stats.html")
#app.route("/playerstats", methods = ["POST"])
def pstatspost():
player_uri = "https://www.balldontlie.io/api/v1/players?search={}%20{}"
playerinput = request.form["nm"]
player_split = playerinput.split()
vn = player_split[0]
nn = player_split[1]
r = requests.get(player_uri.format(vn, nn)).json()
data_group = []
data = {
"player_id": r["data"][0]["id"],
"player_first_name": r["data"][0]["first_name"]
}
data_group.append(data)
print(data_group)
return render_template("stats.html", data=data_group)
inside stats.html:
{% for d in data: %}
<button type="button" class="btn btn-outline-secondary" style="height: 40px; width: 450px; margin-top: 5px; margin-bottom: 5px; border-width: 1px; border-color:lightgrey; text-align: start;">
{{d.player_first_name}} {{d.player_id}}
</button>
{% endfor %}
I hope this works for you aswell!
i have a form that uses a widget. what i want is two vertical columns side by side with the checkboxes.
class MultiCheckboxField(SelectMultipleField):
widget = widgets.ListWidget(prefix_label=False)
option_widget = widgets.CheckboxInput()
class SimpleForm2(Form):
menu_items = MultiCheckboxField('Menu Item', choices=[], coerce=int)
contents = MultiCheckboxField('Content', choices=[], coerce=int)
submit = SubmitField('OK')
for example
Menu Item | Content
cbox1 | cbox1'
This is a Horizontal stacking
This answer did all the work
css stacking

Can anyone tell me how to add a vertical scroll bar to django-tables2 instead of having

{% render_table veh_list %}
<h4> Location database .csv file</h4>
{{ form.locndb }}
<input type="submit" value="Submit" />
</form>
</div>
I've looked all over but I can't seem to get a straight answer, or is there a better table module I can use to display the array and checkboxes?
For anyone in the same boat I figured it out.
I turned disabled pagination
RequestConfig(request, pagination=False).configure(veh_list)
then I wrapped the table in a <div> in the html template
<div style="width: 125px; height: 500px; overflow-y: scroll;">
{% render_table veh_list %}
</div>
The <div> then adds a scrollbar to the whole table interface, I personally would have liked to keep the header constantly at the top but this is the best solution I could come up with.
