I am trying to pass a list called eligable so that I can display on my website but when I run my website it does not display the list. I do not understand what is wrong.
code:
def specificDate(response):
empName = employeeName.objects.all()
eligable = []
if 'checkEmployee' in response.POST:
n = response.POST.get("nameEmployee")
specDate = response.POST.get("date")
if employeeName.objects.filter(employee=n).exists() and Name.objects.filter(date=specDate).exists():
emp = employeeName.objects.get(employee=n)
t = Name.objects.get(name=emp, date=specDate)
overT = Name.objects.filter(name=emp, overtime=True)
for item in overT:
eligable.append(item.date)
checkIn = t.timeIn.strftime("%H:%M:%S")
checkOut = t.timeOut.strftime("%H:%M:%S")
datee = datetime.strptime(specDate,'%Y-%m-%d')
print("Here:: ",t.date)
print("Month:: ",datee.month)
messages.info(response, checkIn + ' - ' + checkOut)
return redirect('/specificDate')
else:
messages.info(response, 'Name does not exist')
else:
pass
return render(response, "main/specificDate.html", context={"empName":empName, "eligable":eligable})
This is the html to print my list:
{% for item in eligable %}
<div class="pad3">
{{item}}
</div>
{% endfor %}
There are two return statements in your code:
return redirect('/specificDate')
and
return render(response, "main/specificDate.html", context={"empName":empName, "eligable":eligable})
The first one is just redirecting without populating context.
The second one does populate context but is reached only when eligable is empty.
I think changing the first return to the second one should solve it.
edit: and you are missing {% endfor %} here. But it should give you an error if you miss it in your complete code.
I've already written a script that parses JSON data from a particular url and stores them into a list. After that I'm able to pass that as an argument to be displayed in my template.
My end goal is to display a table on the template from this JSON data (of which I have currently included only one parameter), for which I believe I need to pass that list into a Django Model.
def index(request):
is_cached = ('raw_json' in request.session)
print(is_cached)
if not is_cached:
# g = {'starttime': '2014-01-01', 'endtime': '2014-01-02', 'minmagnitude': '5'}
g=''
url1 = ul.urlencode(g)
# print(url1)
main_api = 'https://earthquake.usgs.gov/fdsnws/event/1/query?format=geojson&'
final_url = main_api + url1
# print(final_url)
raw_json = requests.get(final_url).json()
string_json = json.dumps(raw_json)
# print(raw_json)
with open('test.txt', 'w') as file:
file.write(string_json)
count = raw_json['metadata']['count']
print('Count: ' + str(count))
maglist = []
placelist = []
for cou in range(0, count):
mag = (raw_json['features'][cou]['properties']['mag'])
maglist.append(mag)
# magdict = dict(list(enumerate(maglist)))
place = (raw_json['features'][cou]['properties']['place'])
placelist.append(place)
# placedict = dict(list(enumerate(placelist)))
# print(placedict)
with open('test2.txt', 'w+') as t1:
for features in raw_json['features']:
coordinates = (features['geometry']['coordinates'])
id = (features['id'])
t1.write("id: %s \n" % (id))
t1.write("coordinates: %s \n" % (coordinates))
# print(singfeature)
for properties, value in features['properties'].items():
t1.write("%s : %s \n" % (properties, value))
# t1.write("\n")
# print (maglist)
args = {'magni': maglist}
print (args)
return render(request, 'earthquake/index.html', args)
The template receives this data with a simple for loop as follows:
{% block content %}
{% for item in magni %}
<p>{{ item }}</p>
{% endfor %}
{% endblock %}
To which the result shows up as follows:
As mentioned previously, I need to display a filterable/sortable table with this parameter (along with other parameters too), so that the end-user may view the data as needed.
I'm quite new to Django.
There is a file api.yml containing a config for ansible:
config/application.properties:
server.port: 6081
system.default.lang: rus
api.pdd.url: "http://{{ stage['PDD'] }}"
api.policy.alias: "integration"
api.order.url: "http://{{ stage['Order'] }}
api.foo.url: "http://{{ stage['FOO'] }}
There is a stage.yml containing the key and the stage values:
default_node:
Order: '172.16.100.40:8811'
PDD: '172.16.100.41:8090'
FOO: '10.100.0.11:3165
In fact, these files are larger and the 'stage' variables are also many.
My task is to parse api.yml and turn it into properties-config. The problem is that I can not pull up the values {{stage ['value']}} I'm trying to do it this way:
stream = yaml.load(open('api.yml'))
result={}
result.update(stream['config/application.properties'])
context= yaml.load(open('stage.yml'))
stage={}
stage.update(context['default_node'])
text = '{% for items in result | dictsort(true)%} {{ items[0] }} = {{
items[1] }} {%endfor%}'
template = Template(text)
properti = (template.render(result=result, stage=stage))
At the output I get this:
server.port = 6081
system.default.lang = rus
api.pdd.url = http://{{ stage['PDD'] }}
api.policy.alias = integration
api.order.url = http://{{ stage['Order'] }}
api.foo.url = http://{{ stage['FOO'] }}
And you need to get this:
server.port = 6081
system.default.lang = rus
api.pdd.url = 172.16.100.41:8090
api.policy.alias = "integration"
api.order.url = 172.16.100.40:8811
api.foo.url = 10.100.0.11:3165
Can I do it with jinja or ansible lib?
Sorry for my bad english
Following this approach, you would need to treat api.yml as a template itself and render it. Otherwise, jinja2 will treat it as a simple value of the property. Something like this would do:
import yaml
from jinja2 import Environment, Template
import json
stream = yaml.load(open('api.yml'))
result={}
result.update(stream['config/application.properties'])
context= yaml.load(open('stage.yml'))
stage={}
stage.update(context['default_node'])
text = """{% for items in result | dictsort(true)%} {{ items[0] }} = {{ items[1] }} {%endfor%}"""
#Then render the results dic as well
resultsTemplate = Template(json.dumps(result))
resultsRendered = json.loads( resultsTemplate.render(stage=stage) )
template = Template(text)
properti = (template.render(result=resultsRendered, stage=stage))
After this you will see the wanted values in the properti var:
' api.foo.url = http://10.100.0.11:3165 api.order.url = http://172.16.100.40:8811 api.pdd.url = http://172.16.100.41:8090 api.policy.alias = integration server.port = 6081 system.default.lang = rus'
It would be nice though if jinja2 was able to render recursively. Maybe spending some time working out with the globals and shared modes of the Environment this can be achieved.
Hope this helps.
I'm using a Django custom template filter as described here to access entries in a 3D array in my template. I pass the 3D array swipeData from views.py to index.html.
index.html:
function getNearestHalfHourTimeString() {
var now = new Date();
var hour = now.getHours();
var minutes = now.getMinutes();
var ampm = "AM";
if (minutes < 15) {
minutes = "00";
} else if (minutes < 45){
minutes = "30";
} else {
minutes = "00";
++hour;
}
return("T" + hour + minutes);
}
var currentDay = (new Date()).getDay();
var currentTimeRounded = getNearestHalfHourTimeString();
{% block content %}
{% load hello_extras %}
var atrium = {{swipeData|bldIndex:'ATRIUMCAFE'|dayIndex:currentDay|timeIndex:currentTimeRounded }};
{% endblock %}
hello_extras.py:
from django import template
register = template.Library()
#register.filter
def bldIndex(List, strIndex):
dctBuild = {'ATRIUMCAFE':0, 'BUTLERCOLLEGE':1, 'CAFEVIVIAN':2, 'CENTERFORJEWISHLIFE':3, 'CHANCELLORGREEN':4, 'CHEMISTRYCAFE':5, 'CONCESSIONS_12':6, 'FORBESCOLLEGE':7, 'FRISTCSTORE':8, 'FRISTGALLERY1':9, 'FRISTGALLERY2':10, 'FRISTGALLERY3':11, 'FRISTGALLERY4':12, 'FRISTWITHERSPOONS':13, 'GRADUATECOLLEGE':14, 'LIBRARY_CART':15, 'MATHEYCOLLEGE':16, 'ROCKEFELLERCOLLEGE':17, 'STUDIO34BUTLEREMPORIUM':18, 'WHITMANCOLLEGE':19, 'WILSONCOLLEGE':20, 'WOODROWWILSONCAFE':21, 'FIRESTONELIBRARY':22}

i = int(dctTime.get(strIndex))
return List[i]
I get the error

How can I use a variable as an argument to my custom template filter? I've tried using a with block already.
Your problem is that you are trying to pass a JS var to a django filter, that it's wrong
currentDay and currentTimeRounded are JS Vars not Python vars, for this reason filter fails
Remember that you can get all necessary info in your view, and then render in your template
I suggest you that format your data in your view and in the template assign it to the respective JS var
some as follow
def some_view(request):
# here you can calculate, convert, create all values to your chart as you need
# if you need time or date can use datetime module ie
values_to_chart = ""
render(request, template_name, locals())
And in your template
var atrium = {{values_to_chart}}
I'm encountering a very strange error. I have an app ID defined in my settings.py file like so:
CARDSPRING_APP_ID = '################'
This works on nearly every page in my site, except for one. Strangely enough, other variables work. In a script section on the page, I have the following:
alert("cs appid=" + {{ CARDSPRING_APP_ID }} +
" sectoken=" + {{ securityToken }} +
" timestamp= " +{{ timestamp }} +
" hash = " + {{ digestedHash }} +
" ccnum " + $('.card-number').val() +
" exp" + $('.expiration-month').val() + $('.expiration-year').val() +
" user = " + {{ csid }});
When the page is rendered, it evaluates to this
alert("cs appid=" + +
" sectoken=" + DDFJRMZXD12WVWHFFC###### +
" timestamp= " +1346183125 +
" hash = " + a929b3aec9179c700c09d###### +
" ccnum " + $('.card-number').val() +
" exp" + $('.expiration-month').val() + $('.expiration-year').val() +
" user = " + SG1###);
Importantly, {{ CARDSPRING_APP_ID }} has evaluated to nothing. Does anyone know why this might be the case? Thank you!
UPDATE
I tried creating a context_processors.py file as described in the answer below, and made sure to add it to the appropriate spot in settings.py . I still don't have any luck -- it evaluates on one page, but not on the other
UPDATE 2
The template is called with this command:
return render_to_response('howto'+str(number)+'.html',locals(),context_instance= RequestContext(request))
UPDATE 3
Got it to work -- needed to add this to my settings.py
TEMPLATE_CONTEXT_PROCESSORS = global_settings.TEMPLATE_CONTEXT_PROCESSORS + (
"myapp.context_processors.cardspring",
)
Create a file called context_processors.py and write the following context processor:
from django.conf import settings
def cardspring(request):
return { 'CARDSPRING_APP_ID': settings.CARDSPRING_APP_ID }
Then add your.location.context_processors.cardspring to TEMPLATE_CONTEXT_PROCESSORS in your Django settings file, where your.location is the location of your context_processors.py file.
