I don't have a lot of experience in Django and I am a fairly green developer. When I run the localhost I keep getting a Internal Error. I have tried most of the solutions to similar problems here and none of them works. Can anyone help me? The code is not mine so I don't want to alter it as such either.
Here is a picture of the errors I keep getting:
The only thing you can do without altering the code is to enter the value "shop_all_art" in the HomePage table in the database.
Do not share code via images. You should also share the related code.
Your stacktrace clearly says, that Python is not able to access first element of HomePage.objects.filter(value='shop_all_art') in file bidgala/bidgala/pages/views.py. all_art_img is most probably empty.
Looks like all_art_img is empty.
you should check if a Query has any elements before with a method such as
if all_art_img.exists():
all_art_img[0]

I have a dataflow flow that appends to an existing bigquery table which has been working for the last few weeks. When i run it now it gives me the error "Cannot run job. Please reload the page and try again." and won't even start the job.
After trying a lot of things, i made a copy of the flow and when the publishing action is creating a new csv file, it works but when i try to
Add a publishing action to an existing big query table,it keeps giving me another bizarre error "SyntaxError: Unexpected token C in JSON at position 0".
I have no idea what is happening since everything used to work perfectly and i made no changes whatsoever.
I am not adding anything new, but I want to give you an answer.
It seems that one of your JSON inputs may be malformed. Try logging it to see what's the problem - and also try skipping malformed JSON strings.
As mentioned in past comments, I suggest to check your logs in StackDriver to find out why are you getting the:
"Cannot run job. Please reload the page and try again."
Also if you can retrieve more information about the error from those logs, It'd be useful to assist you further.
Besides the above, maybe we can solve this issue easier by only just checking the json format, here I put an easy third party json validator and here you can check where you have the error in your json.
I am trying to save an array of text containing category types for a hotel system which looks something like this ['category-1', category-2', category-3, category-4] . I am using category_type = ArrayField(models.CharField(max_length=200),null=True) in my models.py
The error i get is
malformed array literal: "" LINE 1: ..., '{category-1,
category-2}'::varchar(200)[], ''::varcha...
^ DETAIL: Array value must start with "{" or dimension information.
The error persist even after processing python list from ['category-1', category-2', category-3, category-4] to {category-1, category-2, category-3, category-4}.
I have gone through postgresql documentation and have found very limited help,
https://pganalyze.com/docs/log-insights/app-errors/U114 this is something similar posted to what i am facing problem with.
Could someone please tell me what am i doing wrong? Any help would be appreciated.
EDIT:
Following is in my View.py
hotel_category=categoryTable(category_type=categorytype)
hotel_category.save()
and i am using categorytype=request.POST.getlist('category-type') in my Views.py to get it from the POST request after user submits the form. This returns a Python list that i have mentioned above, i have manipulated this list to match PostgreSQL ArrayField with '{','}' but i still have this error. If there is anything else you would like me to add, please let me know. :)
This is an update/answer to my question for anyone who faces this issue in the future. After struggling to find help from different resources, i decided to use JSON string to store my python list.
I am using :
categorytype = json.dumps(request.POST.getlist('category-type'))
to encode and using JSONDecoder() to fetch from database and decode. I have no idea how would this impact my further development but for now it seems a decent approach since personally i think ArrayFields are not well supported and documented in Django.
I will keep this post updated as i progress further on how this approach has impacted my development.
Have a nice day.
I have a project that is my first serious dive into Mongoid.
I saw a tip to use the following command:
Parent.where('childrens._id' => Moped::BSON::ObjectId(params[:id])).first
But this doesn't work. Error message was:
NameError: uninitialized constant Moped::BSON
I found that BSON is no longer included, so I added it to my Gemfile, as well as Moped. Then, I did another fix I found (placing Moped::BSON=BSON in application.rb).
This still didn't work, but the error changed to:
NoMethodError: undefined method `ObjectId' for BSON:Module
So I am assuming that this method got deprecated or something. Does anyone have any other tips?
Just to be clear, I am finding myself in the situation where I want to sort embedded documents using jquery-sortable. This requires me to update them in the database, but the serialize from that doesn't include the parent document in the hash. So I figured I'd try to get it on the back end using an ID from the embedded document. That is why I need it.
Thanks again for any help you can provide.
Try simply:
Parent.where('childrens._id' => params[:id]).first
I have solved the question though this won't be of much help to people in the future. The requirements have changed and now I am using human-readable strings as IDs to assist in friendly URLs and some other stuff.
Therefore, I don't have any issues with ObjectIds. Cortex's solution should (from what I have read) work for dealing with ObjectIds but I cannot verify it now.
If I got to calendar, click on To Do, then try to add an event, the form pops up, I fill it out, press save, but no Event gets added.
In the SQL error log's I see an error like this:
2011-09-29 14:57:07 EDT ERROR: null value in column "visibility" violates not-null constraint
2011-09-29 14:57:07 EDT STATEMENT: insert into
vtiger_activity(activityid,subject,date_start,time_start,time_end,due_date,status,eventstatus,priority,sendnotification,activitytype,visibility,duration_hours,duration_minutes,location,recurringtype,notime)
values('235','Testing','2011-09-29','19:50',NULL,'2011-09-29','Not Started',NULL,'High','0','Task',NULL,NULL,NULL,NULL,NULL,'0')
So, for some reason, it is trying to add a To-Do while inserting null values. My biggest problem is that I cannot locate the origin of the query. So, basically, the most important thing I am asking is what file takes the data that was input into the todosave form and turns it into a query.
I don't know if many people on here use Vtiger, but I couldn't figure this out so I went ahead and posted anyway. The official documentation is not very helpful in my opinion.
Thanks for everything, have a good day.
This might be an isolated case, but was any of the modules modified recently? In this case, I would assume that it would be the Calendar module. I've tested this on the demo website and on my vTiger installation and it works fine..
Perhaps you can download a fresh copy of vTiger and replace the modules/Calendar all its content.
By the way, another place to ask if you have any questions, is the vTiger forums.

Usually you can ask it in the Help - 5.2.1 section. Hope this helps!
The goal is to make users be more specific when reporting a bug.
Ususally I get a messy report "It doesn't work, please help ASAP!" from a user, so I keep asking the same questions each time -- "The why, the who-what-when, the where, and the how..."
Instead, I want to set a template for a new issue, something like this:
What page did you go? What login did you use?
What did you see?
What did you expect to see?
Why do you think this is a bug?
or whatever.
Is it possible?
This plugin would be very helpful, in your case,
Issue Templates- http://www.redmine.org/plugins/issue_templates
here is a patch for templating issue descriptions. anything beyond that is still underway, and is relevant to the issue mentioned above.
http://www.redmine.org/issues/2931
The link below says that you can for the last year or so:
http://www.redmine.org/issues/1138
But I haven't yet found a description of how this functionality is used. I guess I'll have to slog through some code to find out.
Maybe a possible workaround is to have an issue to use as a template.
Create an issue like this:
name: Bug template
description:
What page did you go?
What login did you use?
What did you see?
What did you expect to see?
Why do you think this is a bug?
Then you can duplicate it each time you need a real issue.
The limit is with issues with subtasks. If you duplicate the parent issue you don't get the subtasks duplicated as well.
