For loop in Django - django

Question

I have two question. First question: Python script that shows me the precipitation for a certain period.For example, I'm getting an initial year-month and a final year-month.
Initial:
year:2000
month:3
Final
year1:2005
month:4
Now, instead of seeing:
2000/3,2000/4,2000/5,2000/6..........2005/1,2005/2,2005/3,2005/4
she works like this(look in the hooked picture):
2000/3, 2000/4, 2001/3, 2001/4........2005/3,2005/4.
I want to work for me like the first case.
def period_month_prec(year,month,year1,month1):
for i in range (year,year1+1,1):
for j in range(month,month1+1,1):
......................
Second question: How to write the output(picture) from the script in csv.fileenter image description here
This is what my views.py script looks like , which saves me only the first result:
def monthly_period(request):
if request.method == "POST" :
form = PeriodMonthlyForm(request.POST)
if form.is_valid():
data = form.cleaned_data
year = data.get('year')
month = data.get('month')
year1 = data.get('year1')
month1 = data.get('month1')
lon = data.get('lon')
lat = data.get ('lat')
inter = data.get('inter')
point = period_month_prec(year,month,year1,month1,lon,lat)
args = {'point':point}
response = HttpResponse(content_type='text/txt')
response['Content-Disposition'] = 'attachment; filename="precipitation.txt"'
writer = csv.writer(response)
writer.writerow([point])
return response
else:
form = PeriodMonthlyForm()
active_period_monthly = True
return render (request, 'carpatclimapp/home.html',{'form':form, 'active_period_monthly': active_period_monthly})

Answer 1

Ok, i have forms like this:
Forms
You set initial values(red color) and end interval(blue color). For this given interval, the lon and lat are defined for the point in which we want to perform interpolation. When you press the submit button, it starts with interpolation for a defined period. The loop problem is because it works only for the defined months (we see from the 2nd picture that it only works in the interval 1-6) but not for 7,8,9,10,11,12 months between these years.
Initial: year:2000, month:3
Final: year1:2001, month:4
for this she's doing it like this: 2000/3,2000/4,2001/3,2001/4
I do not want that, I want this: 2000/3,2000/4,2000/5,2000/6,2000/7.....2000/12,2001/1,2001/2,2001/3,2001/4.
this is me code :
def period_month_prec(year,month,year1,month1,lon,lat):
cnx = sqlite3.connect(DB1)
cursor = cnx.cursor()
table = 'monthly'
year = int(year)
year1 = int(year1)
month = int(month)
month1 = int(month1)
for i in range (year,year1+1,1):
for j in range(month,month1+1,1):
query = '''
SELECT dates, cell, prec FROM %s WHERE dates = "%s-%s" ;
''' % (table,i,j)
df = pd.read_sql_query(query, cnx)
tacka = '''SELECT id, lon, lat,country,altitude FROM %s;''' % 'grid1'
grid1 = pd.read_sql_query(tacka, cnx)
podaci = pd.merge(df,grid1,left_on='cell',right_on='id')
podaci_a = podaci.drop(['cell','id','country','altitude'],axis=1)
lon_n = podaci_a['lon'].values
lat_n = podaci_a['lat'].values
prec =podaci_a['prec'].values
x_masked, y_masked, prec_p = remove_nan_observations(lon_n, lat_n, prec)
xy = np.vstack([x_masked,y_masked]).T
xi = ([lon,lat])
inter_point = interpolate_to_points(xy,prec_p,xi, interp_type='linear'
return (i,j,lon,lat,inter_point)
The results that come out look like this:
loop with calculations
The second question was how to save these results(2nd picture) in the csv file, how to write correctly views.py. Currently she looks like this :
def monthly_period(request):
if request.method == "POST" :
form = PeriodMonthlyForm(request.POST)
if form.is_valid():
data = form.cleaned_data
year = data.get('year')
month = data.get('month')
year1 = data.get('year1')
month1 = data.get('month1')
lon = data.get('lon')
lat = data.get ('lat')
inter = data.get('inter')
point = period_month_prec(year,month,year1,month1,lon,lat)
args = {'point':point}
response = HttpResponse(content_type='text/txt')
response['Content-Disposition'] = 'attachment; filename="precipitation.txt"'
writer = csv.writer(response)
writer.writerow([point])
return response
else:
form = PeriodMonthlyForm()
active_period_monthly = True
return render (request, 'carpatclimapp/home.html',{'form':form, 'active_period_monthly': active_period_monthly})
I hope I'm a little clearer now
