Hey guys I'm having the WEIRDEST issue while pairing on this rails app. We're using google maps api to grab lat and lng to do an ActiveRecord look up. For some odd reason the SomeModel.where("lat <=?", neLat) will not work BUT when I print neLat to the console and then copy the number and then hard code it to that query it works perfectly! I'm so stumped. Has anyone had any issues like this before?
This is an example of what I'm currently doing which doesn't work:
data = request.parameters
neLat = data['neLat'].to_f
#props = SomeModel.where("lat <=?", neLat)
47.6090933689332 is the number I see in my console/ActiveRecord query. One troubleshooting step I've taken was hard coding the number into a variable like this:
neLat = 47.6090933689332
#props = SomeModel.where("lat <=?", neLat)
I get the results I'm looking for this way, but I don't want to be hardcoding these coordinates. Another troubleshooting step I've taken was to make sure there wasn't a conflict with the float value so I went with this:
temp = "47.6090933689332"
neLat = temp.to_f
#props = SomeModel.where("lat <=?", neLat)
This didn't work either as it gave me the same results as the example just above.
EDIT:
I've provided more details as requested in the comments. Also, I realized I wasn't as clear as I could've been in my initial question. When I query I'm able to get my desired results back in the console, but the problem lies in the rendering of the results in my view. Any form of hardcoding will render correctly in my view, but when I use the values from my request.parameters is where the rendering fails. It will either render everything in the table or nothing in the table. So in the example below I can see that I'm getting 3 different properties from my properties table, but my view will render EVERYTHING in my table, which is like 7 properties.
Here is the raw sql query that ActiveRecord generates (this is the result of all 3 ways as I've done above):
SELECT `properties`.* FROM `properties` WHERE (lat >= 47.609093368933195)
#<Property:0x007fa333ac1880>
#<Property:0x007fa333ac1718>
#<Property:0x007fa333ac15b0>
As for the schema, it's just one table that I'm using and no joins.

I've been refactoring an existing Umbraco project to use more performant querying when getting back document data as everything was previously being returned using LINQ. I have been using a combination of Umbraco's querying via XPaths and Examine.
I am currently stumped on trying to get child documents using the Umbraco.ContentAtXPath() method. What I would like to do is get child document based on a path I parse to the method. This is what I have currently:
IEnumerable<IPublishedContent> umbracoPages = Umbraco.ContentAtXPath("//* [#isDoc]/descendant::/About [#isDoc]");
Running this returns a "Object reference not set to an instance of an object." error and unable to see exactly where I'm going wrong (new to this form of querying in Umbraco).
Ideally, I'd like to enhance the querying to also carry out sorting using the non-LINQ approach, as demonstrated here.
Up until Umbraco 8, content was cached in an XML file, which made XPath perfect for querying content efficiently. In v8, however, the so called "NuCache" is not file based nor XML based, so the XPath query support is only there for ... well... Old times sake, I guess? Either way it's probably not going to be super efficient and (I'd advise) not something to "aim for". That said I of course don't know what you are changing from (Linq can be a lot of things) :-/
It certainly depends on how big your dataset is.
As Umbraco has moved away from the XML backed cache, you should look into Linq queries against your content models. Make sure you use ModelsBuilder to generate the models.
On a small dataset Linq will be much quicker than examine. On a large dataset Examine/Lucene will be much more steady on performance.
Querying NuCache is pretty fast in Umbraco 8, only beaten by an Examine search.
Assuming you're using Models Builder, and your About page is a child of Home page, you could use:
var homePage = (HomePage) Model.Root();
var aboutPage = homePage?.Children<AboutPage>().FirstOrDefault();
var umbracoPages = aboutPage.Children();
Where HomePage is your home page Document Type Alias and AboutPage is your About page Document Type alias.
totally new here & figured you guys will know the answer before I can even come near figuring this out.
I have a google form, feeding a live google sheet which users submit car reg numbers.
My goal is to have the reg number display the make, model besides the reg.
I have implemented an importXML function & the cell I expect to see the data loads up for a few minutes, then reverts to "N/A" or sometimes doesn't pull the data at all, but manually visiting the URL does return the data.
The import XML function uses a cell, made up of URL string, then adds the Reg/VIN input by form submission. That cell looks something like this "basicvehicledetails.com/reg" and returns the Class on the webpage relevant for Make/Model in separate cells.
I need the data to stay once it is returned, but don't know how to do that.
Another option is a car check website that requires a login, and then the reg to be input & searched before a webpage returns in-depth data on the car, is this something I can get to export to google sheet/excel spreadsheet?
I'm really stuck for this one, and would really appreciate any help as updating each car manually is painful.
try like:
=REGEXREPLACE(QUERY(ARRAY_CONSTRAIN(IMPORTDATA(
"https://www.motorcheck.ie/free-car-check/?vrm=152D1234"),5000,1),
"where Col1 contains 'dark-left'", 0), "</?\S+[^<>]*>", )
UPDATE:
=IMPORTHTML("https://www.cartell.ie/ssl/servlet/beginStarLookup?registration=152D1234",
"table", 1)
So I have a form and a table called Variables. The table is simply the fields VarID, VarDescription, and VarValue. It's only three items that are all network locations of things. The VarValue is the only thing that can be changed through the form, and thus it is the only thing validated. I validate those records on the form with the Before Update Event in the control by using logic such as:
If Me.VarID = 1 Then
If Me.Tex like "*:\* Then....
End If
If GetAttr(Me.Tex) = vbDirectory Then
End
End If
If Me.VarID = 2 Then
If Me.Tex like "*:\* Then....
End If
If GetAttr(Me.Tex) = vbNormal Or GetAttr(Me.Tex) = vbArchive Then
End If
End If
This all works great. However my issue comes in when multiple locations become invalid at once. I get stuck in one cell because the other VarValue's are invalid as well. How can I validate only the cell I have changed? I tried playing around with various Dirty and Focus events/methods, but those seem to be form specific, not cell specific.
This seems to just be a reference issue as I am looking on the database on two completely separate networks. The original uses all Office 16.0 libraries whereas the instance I was having the issue with was using Office 15.0 libraries. I played around with the original and it works fine, even if all the locations become bad at the same time.
This is not working as we discussed previously, for some reason and I have done is create some $vars for the uploaded file.
Code available here (Pastebin).
But never actually inserts anything
When doing a var_dump($csv_row) i get: bool(false)
var_dump($fh) shows: resource(89) of type (stream)
var_dump($insert_str) shows all 1700 records from the csv file (obviously too big to post on here)
So I’m guessing the while statement or the whole from if statement is wrong somewhere. Really really would appreciate some help on this, I need to get it working by tomorrow (monday)
You seem to be using the codeigniter database library wrong. I can see a
$this->db->set($insert_str);
but no $this->db->insert() to be found. The set() method only useful with an update() or insert() following it, See the docs, search for $this->db->set().
You either want to use the $this->db->insert_batch() (on the same doc page, unfortunately no direct links for sections) form and build up an array of arrays with your records (so you won't have to create a long sql string either).
Or you can use the $this->db->query() and just feed the $insert_str to it where you now call $this->db->set().
According to your question:
var_dump($insert_str) shows all 1700 records from the csv file
So i would rule out the possibility of the while loop or the if not working.
Put this code at the top of the controller or before reading csv file
ini_set('auto_detect_line_endings', true);
Check if this will work for you
Currently I'm developing a debate module (much like a scrum/kanban board) for a GPL application (e-cidadania) and I don't have any experience with complex backends. I have developed a basic frontend for it, but now I don't know what approach I should use for the ajax and django backends to save and manipulate the table and notes.
The table can be N rows and N columns, every row and column has a name and position inside the table. Every note has also a position, text and comments (managed with the django comments framework).
I thought to store the parent element of every note (so I can place it later) and store the name of the rows and columns like CSV strings. Is that a good approach?
A screenshot of the current frontend: http: //ur1. ca/4zn4h
Update: I almost forgot, the frontend has been done with jQuery Sortables (so the user can move the note around as he likes) and CSS3.
You just need to model your domain (that is, debates that look like scrum boards) within Django. Think about it in plain English first, like this:
The has debates. These consist of criteria, organised in rows and columns in a specific order. This creates cells, which can have notes inside them.
Then you can set to work translating this into model classes. Don't worry too much about the fields they contain, the most important bit is the relationships (so the ForeignKey bits):
class Debate(models.Model):
title = ...
class Column(models.Model):
title = ...
order = ...
board = models.ForeignKey(ScrumBoard, related_name='columns')
class Row(models.Model):
title = ...
order = ...
board = models.ForeignKey(ScrumBoard, related_name='rows')
class Cell(models.Model):
column = models.ForeignKey(Column)
row = models.ForeignKey(Row)
class Note(models.Model)
text = ...
cell = models.ForeignKey(Cell)
That might be overly complex for what you need, though. I'm not an expert in the problem you're trying to solve? My suggestion, Django is quick – so start hacking, and give it a go, and if it's all wrong then you can go back a few steps, clean out your database and try again.
You might find it useful to play with South, which does database migrations for when you do things like add/remove/edit fields in your models.
