I'm new to Swift and programming in general.
I'm working on a small OSX application that displays information for countries when the user clicks on a map of the world. The map interface works fine. I've tried this on a smaller map with just four countries. I've put my country data into a class called Country with variables for the data (e.g. population, landArea, majorExport, etc.) I put the Countries into an array. When the user selects a country, the controller grabs the right Country from the array and populates the data fields. So far, so good.
I'm getting ready to scale up to a map of the world with 150+ countries. Is there a way to store all of my data in a separate file (like a .csv file) so I don't have to hard code all of this Country data directly in a .swift file? If so:
(a) what kind of file should I use?
(b) how would I set it up?
(c) how do I get the application access it?
Thank you.
Now that I think about it, you can use a .plist file. It's the easiest, because you can simple use dict.writeToFile: to write and NSDictionary(contentsOfFile:) to read. And since NSDictionary is bridged to Swift, it just works. I found this great article

Trying to save an h2o model with some specific name that differs from the model's model_id field, but trying something like...
h2o.save_model(model=model,
path='/some/path/then/filename',
force=False)
just creates a dir/file structure like
some
|__path
|__then
|__filename
|__<model_id>
as opposed to
some
|__path
|__then
|__filename
Is this possible to do from the save_model method?
I can't / hesitate to simply change the model_id before calling the save method because the model names have timestamps appended to them to avoid name collisions with other models that may be on the h2o cluster (am trying to remove these timestamps when saving on disk and simplifying the name on the cluster before saving creates a time where naming collision can occur if other processes are also attempting to save such a model (of, say, a different timestamp)).
Any way to get this behavior or other common alternatives / workarounds?
This is currently not possible, however I created a feature request here. There is a related question here which shows a solution for R (could be adapted to Python). The work-around is just to rename the file manually using a few lines of R/Python code.
I am trying to list the view template’s properties so we can compare them with another old template.
For example what model elements are hidden or have overrides in a given template or which Revit links have been hidden or overridden in a given template.
View Template
(https://www.google.com/search?q=view+template+revit&rlz=1C1GGRV_enUS770US770&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjLndrd2cTbAhVESq0KHX1cAPwQ_AUICygC&biw=1536&bih=824#imgrc=Q0v-pV7Nxl4kfM:)
I’m looking to devise a View Template Compare tool and access to the owner and creator of them.
public void ApplyViewTemplateToActiveView()
{
Document doc = this.ActiveUIDocument.Document;
View viewTemplate = (from v in new FilteredElementCollector(doc)
.OfClass(typeof(View))
.Cast<View>()
where v.IsTemplate == true && v.Name == "MyViewTemplate"
select v)
.First();
using (Transaction t = new Transaction(doc,"Set View Template"))
{
t.Start();
doc.ActiveView.ViewTemplateId = viewTemplate.Id;
t.Commit();
}
}
With Revit API you can access with:
GetTemplateParameterIds Method / ViewTemplateId Property
The Revit API exposes almost all the ViewTemplate properties.
For instance this method returns all the Visibility/Graphic Overrides for a specific category:
https://apidocs.co/apps/revit/2019/ed267b82-56be-6e3b-0c6d-4de7df1ed312.htm
The only thing I couldn't get for a ViewTemplate are the "includes", but all the rest seems to be there.
Update:
The list or properties "not included" can be retrieved with GetNonControlledTemplateParameterIds().
Yes, and no.
Yes, I guess you can use Forge Model Derivative API to export RVT file and then build a dashboard around the View Templates data. That's assuming that View Templates data actually gets exported when the model is translated. That data is not attached to any geometry so I would not be surprised if it was skipped. The question here is why? This is like renting a 16-wheel truck to move a duffel bag across the street.
No, if your intention is to directly interact with the RVT model. Forge can view it, but to push anything back or request changes to the model, is not available yet. Then again, I am not even sure that the view template data is available via model derivative exports.
This brings me another alternative. Why not just collect the data using Revit API, the standard way and then push it out to a Database and build on top of that? There is no reason to employ Forge for any of that.
Thanks Jeremy, I had dig into your amazing website and also some solution that Konrad post in the Dynamo Forum about this. In Revit seems pretty achievable, you filter the View that is View Template and then extracts these properties, is it correct?.
I am wondering if someone can point me in the right direction with Forge.
Some amazing guys are developing a BQL https://www.retriever.works/.
BQL(Building Query Language) is a query language for buildings, similar to how SQL is a query language for databases. It is fast and flexible. BQL helps improve efficiency for QA/QC (quality assurance and quality control), and building data extraction without leaving Revit. I am also trying these and I would like to understand if there are some works where I could start with Forge next week about this.
So I'm trying to make a data editor for an iOS/Android app I've got. There's 3 separate data files that I'd like to be able to edit, and I would like to save them to plist files or xml files. I'm planning on using Core Data in the app. The problems I'm running into:
1). Should this be a Document-Based Application or not?
2). If so, how would I set it up to allow editing of 3 different structures of files?
3). And if so, how would I go about setting the document based app to use regular plist/xml files as the file type instead of some custom file type?
The plan is for the editor to be able to open up and edit the files, and then the saved files can be copied into the project resources of the iOS and Android apps.
1. Should the app be document-based?
Yes.
2. How would one allow editing three different structures of files?
Choose from any of the following:
Create three dictionaries in the document types list, all three of which reference the same document class.
The same as above, but with windowNibName or makeWindowControllers choosing the UI depending on the document type. In other words, shared model code, but different view hierarchies. (I probably would choose either of the alternatives instead.)
Create three document type dictionaries, each of which has its own document class.
Which one you choose will depend on just how different the types are.
You'll probably want to export a UTI for each document type, as well. Xcode will not help you there; you'll need to write each UTI dictionary by hand.
3. How would I set the document based app to use regular plist/xml files as the file type instead of some custom file type?
If you export one or more UTIs, you should set the parent UTI(s) of each UTI appropriately, but that's advisory; all it means is you'll be able to open the documents with generic plist or XML editors/viewers.
Reading in and writing out the data is up to you, in each document class. You will have to use NSPropertyListSerialization, NSXMLParser, PRHXMLParser, NSXMLDocument, or something else, as you see fit; NSDocument does not handle your file format for you.
I am porting a JAVA game to WP7. We have lots of images in our game and for loading them in JAVA use a function something like this "Resources.getImage(IMG_BULLETS);" where IMG_BULLETS is ID(an int) of the image.
But in WP7 we have to pass the path(a string) of image in order to load that.
Now my question is :
How to achieve a int-String mapping? so that I dont have to manually change the Id into path.
One possible solution comes in my mind is to have a .txt file having image path and its Id and parse that. But I am sure their is much better solution for this.
Note : we also have a multi-level folder structure for images and other files.
If you really want to refer to resources by int, you are going to have to map them some how to their path. As far as I know, there is no way to crawl your assets, and even if you could, i some how doubt you will get the same index order and you would have to redo your enum.
There are going to be a few hurdles you hit with trying to port and code changes. Another one, (one you will still have even with a txt file work around) will be that the contentManager.Load takes a type, eg, contentManager.Load<Texture2D>('path') returning a Texture2D.
One option would be to create your own singleton 'Resources' class that has get methods that take int to get the appropriate asset, however you will still need a mapping via xml or txt file of somekind. However this will require all your assets being loaded from the start which are more problems of their own (90mb memory limit and really long load time).
My advice would be look at the game development section of the App Hub and have a look at the game state example to help you see how you might be able to structure your game to work well with XNA.
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.
