The same method works; if I get rid of a specific value of a key.
I have a field called 'Feature' which helps me get items descriptions from amazon; I've made sure it works correctly by printing. It's a plain string; I've made sure and double checked it. Using type()
This is how I'm setting flask session dictionary:
app = Flask(__name__)
app.config['SECRET_KEY'] = 'yo'
@app.route('/', methods=['GET','POST'])
def index():
authenticated_url = authenticate(Availability='Available',Operation='ItemSearch',Keywords=str(query),SearchIndex='Electronics', ResponseGroup='ItemAttributes')
product = authenticated_url['ItemSearchResponse']['Items']['Item']
arr = []
for items in product:
main_dictionary = {}
sub_dictionary = {}
sub_dictionary['price'] = items['ItemAttributes']['FormattedPrice']
featureLists = items['ItemAttributes']['Feature']
emptyFeatureStr = ' '
for items in featureLists:
emptyFeatureStr += items
sub_dictionary['Feature']=emptyFeatureStr
main_dictionary[items['ASIN']]=sub_dictionary # I construct a dictionary whose key is ASIN number and values
arr.append(main_dictionary) #I append my new dictionary into an array.
session['searchResults']=arr
print session['searchResults']
#Here I try to set the flask session dictionary key to searchResults
# Verfied/made sure that this is set correct; up until here everything works; my dictionary is set as expected.
ISSUE:
@app.route('/profile/<asin>', methods=['GET','POST'])
def profilePage(asin):
return str(session.get('searchResults')
When I do that it gives me null. The moment I get rid of feature it seems to be working as expected... like the price is displayed and amazon calls; and flask session is set properly. I have no idea the momment I set feature key/value it stops working.
This is an example of what is being passed into feature
