I have a Django web site which I want ot be viewable in different languages. Until this morning everything was working fine. Here is the deal. I go
to my say About Us page and it is in English. Below it there is the change language button and when I press it everything "magically" translates
to Bulgarian just the way I want it. On the other hand I have a JS menu from which the user is able
to browse through the products. I click on 'T-Shirt' then a sub-menu opens bellow the previously pressed containing different categories - Men, Women, Children. The link guides me
to a page where the exact clothes I have requested are listed. BUT... When I try
to change the language THEN, nothing happens. I go
to the Abouts Page, change the language from there, return
to the clothes catalog and the language is changed...
I will no paste some code.
This is my change button code:
function changeLanguage() {
if (getCookie('language') == 'EN') {
setCookie("language", 'BG');
} else {
setCookie("language", 'EN');
}
window.location.reload();
}
These are my URL patterns:
urlpatterns = patterns('',
# Example:
# (r'^enter_clothing/', include('enter_clothing.foo.urls')),
# Uncomment the admin/doc line below and add 'django.contrib.admindocs'
#
to INSTALLED_APPS
to enable admin documentation:
# (r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line
to enable the admin:
(r'^site_media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': '/home/boris/Projects/enter_clothing/templates/media', 'show_indexes': True}),
(r'^$', 'enter_clothing.clothes_app.views.index'),
(r'^home', 'enter_clothing.clothes_app.views.home'),
(r'^products', 'enter_clothing.clothes_app.views.products'),
(r'^orders', 'enter_clothing.clothes_app.views.orders'),
(r'^aboutUs', 'enter_clothing.clothes_app.views.aboutUs'),
(r'^contactUs', 'enter_clothing.clothes_app.views.contactUs'),
(r'^admin/', include(admin.site.urls)),
(r'^(\w+)/(\w+)/page=(\d+)', 'enter_clothing.clothes_app.views.displayClothes'),
)
My About Us page:
@base
def aboutUs(request):
return """<b>%s</b>""" % getTranslation("About Us Text", request.COOKIES['language'])
The @base method:
def base(myfunc):
def inner_func(*args, **kwargs):
try:
args[0].COOKIES['language']
except:
args[0].COOKIES['language'] = 'BG'
resetGlobalVariables()
initCollections(args[0])
categoriesByCollection = dict((collection, getCategoriesFromCollection(args[0], collection)) for collection in collections)
if args[0].COOKIES['language'] == 'BG':
for k, v in categoriesByCollection.iteritems():
categoriesByCollection[k] = reduce(lambda a,b: a+b, map(lambda x: """<li><a href="/%s/%s/page=1">%s</a></li>""" % (translateCategory(args[0], x), translateCollection(args[0], k), str(x)), v), "")
else:
for k, v in categoriesByCollection.iteritems():
categoriesByCollection[k] = reduce(lambda a,b: a+b, map(lambda x: """<li><a href="/%s/%s/page=1">%s</a></li>""" % (str(x), str(k), str(x)), v), "")
contents = myfunc(*args, **kwargs)
return render_to_response('index.html', {'title': title, 'categoriesByCollection': categoriesByCollection.iteritems(), 'keys': enumerate(keys), 'values': enumerate(values), 'contents': contents, 'btnHome':getTranslation("Home Button", args[0].COOKIES['language']), 'btnProducts':getTranslation("Products Button", args[0].COOKIES['language']), 'btnOrders':getTranslation("Orders Button", args[0].COOKIES['language']), 'btnAboutUs':getTranslation("About Us Button", args[0].COOKIES['language']), 'btnContacts':getTranslation("Contact Us Button", args[0].COOKIES['language']), 'btnChangeLanguage':getTranslation("Button Change Language", args[0].COOKIES['language'])})
return inner_func
And the catalog page:
@base
def displayClothes(request, category, collection, page):
clothesToDisplay = getClothesFromCollectionAndCategory(request, category, collection)
contents = ""
pageCount = len(clothesToDisplay) / ( rowCount * columnCount) + 1
matrixSize = rowCount * columnCount
currentPage = str(page).replace("page=", "")
currentPage = int(currentPage) - 1
#raise Exception(request)
# this is for the clothes layout
for x in range(currentPage * matrixSize, matrixSize * (currentPage + 1)):
if x < len(clothesToDisplay):
if request.COOKIES['language'] == 'EN':
contents += """<div class="clothes">%s</div>""" % clothesToDisplay[x].getEnglishHTML()
else:
contents += """<div class="clothes">%s</div>""" % clothesToDisplay[x].getBulgarianHTML()
if (x + 1) % columnCount == 0:
contents += """<div class="clear"></div>"""
contents += """<div class="clear"></div>"""
# this is for the page links
if pageCount > 1:
for x in range(0, pageCount):
if x == currentPage:
contents += """<a href="/%s/%s/page=%s"><span style="font-size: 20pt; color: black;">%s</span></a>""" % (category, collection, x + 1, x + 1)
else:
contents += """<a href="/%s/%s/page=%s"><span style="font-size: 20pt; color: blue;">%s</span></a>""" % (category, collection, x + 1, x + 1)
return """%s""" % (contents)
Let me explain that you needn't be alarmed by the large quantities of code I have posted. You don't have
to understand it or even look at all of it. I've published it just in case because I really can't understand the origins of the bug.
Now this is how I have narrowed the problem. I am debuging with "raise Exception(request)" every time I want
to know what's inside my request
object. When I place this in my aboutUs method, the language cookie value changes every time I press the language button. But NOT when I am in the displayClothes method. There the language stays the same. Also I tried putting the exception line in the beginning of the @base method. It turns out the situation there is exactly the same. When I am in my About Us page and click on the button, the language in my request
object changes, but when I press the button while in the catalog page it remains unchanged.
That is all I could find, and I have no idea as
to how Django distinguishes my pages and in what way.
P.S. The JavaScript I think works perfectly, I have tested it in multiple ways.
Thank you, I hope some of you will read this enormous post, and don't hesitate
to ask for more code excerpts.
