Sometimes I'll forget to compile a tiny new image icon or something, and rather than just sending a bad URL to the browser so it can display the little box with a ?, the asset pipeline crashes my entire application. I think this is a little bit overkill. I'd rather have the asset pipeline "fail gracefully" if that's possible. Is there a setting that will disable raising errors in production? Thx!
Hi you can disable asset pipeline by setting
config/application.rb
from
config.assets.enabled = true
to
config.assets.enabled = false
you can also refer to this guide:

Am trying to load a local TileFile layer in pydeck(0.5) in jupyter notebook
I am using the following code:
import pydeck as pdk
data ='https://localhost:/home/user/myfolder/tiles/{z}/{x}/{y}.png`
layer = pdk.Layer(
'TileLayer', # `type` positional argument is here
data=data
)
# Set the viewport location
view_state = pdk.ViewState(
longitude=50,
latitude=50,
zoom=0,
min_zoom=0,
max_zoom=5,
pitch=40.5,
bearing=-27.36)
# Combined all of it and render a viewport
r = pdk.Deck(layers=[layer], initial_view_state=view_state)
r.to_html('TileLayer-example.html'
This just creates a blank view window in Jupyter where it should show an image.
If I take launch the TileLayer-example.html independently into a browser I also get a blank window, However browser (Firefox) console output is as follows:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://localhost:/home/user/myfolder/tiles/0/0/0.png. (Reason: CORS request did not succeed).
TypeError: NetworkError when attempting to fetch resource. tile-layer.js:18:56

t tile-2d-header.js:90
u runtime.js:45
_invoke runtime.js:271
e runtime.js:97
Babel 2
r
u
I am not sure if the problem is CORS related (calling a local file) or if my data path is just plain wrong? I have tried may variants on path but all seem to have the same console warning issues.
Any suggestions for simple safe ways around the CoRs problem, or suggestions for accessing local TileFiles in PyDeck would be much appreciated
For other folk currently looking to implement TileLayer in Pydeck. It appears TileLayer is not yet documented or currently supported in pydeck and can only be achieved with a custom layer see this github issue and this suggested workaround with a custom layer
With respect to the CoRs issue of trying to display a local file resource in the browser when called from a URL. if you are looking for a quick fix to do a test/debug then in Firefox: the suggestions here help. For Firefox specifically they suggest the following:
go to about:config
search for privacy.file_unique_origin
set it to false.
Note this is a security risk so reset it to true after debugging.
The only workable solution currently seems to be to put the tilefile in the working directory from which your deck project is launched
I am playing around with the new UI testing introduced in Xcode 7 beta. In one of my UI testing scenarios, I need to add some code that does the same thing as clicking Simulator -> Reset Content and Settings in the setup() of my test file, which is a XCTestCase. Can the reset be done programmatically? Or, can we mimic the effect of a factory reset on an app in test code?
Not entirely programmatically, but you can always write a bash file to delete:
${user.home}/Library/Application Support/iPhone Simulator/${simulator.version}
That will clear the settings on the simulator.
My understanding is that you won't be able to that from within your app, as apps are sandboxed.
Usually people were using shell scripts or apple scripts. However, using hard reset is absolutely not necessary.
You shouldn't care about data in other apps, you should care only about the data in your app. You can always delete your app data (files, user defaults) in the beginning of your tests. So, why should you do a hard reset?
A better solution is mocking. If your test supposes that, for example, some variable in NSUserDefaults is not set, you don't have to care about the actual value stored there, just mock the method your implementation is using (e.g. objectForKey: and let it return nil.
I'm fairly new to Express and am having an issue. I have node_env set to production and app.get('view cache') is returning true. However, it doesn't appear to be caching my jade baseed views. I can see get with a 304, but my view render is still being called every time.
Am I misunderstanding what this setting is for?
Edit: I guess this setting is really just to make views templates perform better in production. Am I to assume then the express does not support caching of dynamically generated view content?
I noticed adding res.header('Cache-Control', 'max-age=60, must-revalidate');
Is there a cleaner way to do this? thanks
When the 'view cache' setting is true, it caches the compiled javascript of the jade templates.
It doesn't however, cache the jade into a fully static document.
If you wished to do this, you could render the jade once in your app and store the result as a file or in memory. Then you just serve this rendered jade to your client.
I'm developing a Rails app using the rails s WEBrick server. For some reason, even though I'm in development mode, one of my controller classes looks like it's still being cached since the controller's class variable values are persisting between page requests.
Is this an expected behavior, considering that in my config/environments/development.rb file, I have the following settings?
config.cache_classes = false
config.action_controller.perform_caching = false
Thanks!
UPDATE: Really, I'm mostly looking to understand why the controller's class variables continue to store their values between page requests when I'd expect those values to be cleared every time I navigate to a new page.
By default, Rails reloads classes only if they change. This can be changed by setting
config.reload_classes_only_on_change = false
This should reload the classes on every request and reinitialize the class variables.
I'm currently experiencing problems with static content - most noticeably jQuery datepicker images, but also other static files - which results in images/static content loaded many times - I can clearly see it in IE6 status bar (not to mention SLOW rendering).
The problem and possible solutions seems to be described here: http://www.explainth.at/en/tricks/flickfix.shtml. However, I use IIS6 not Apache, and static files that I don't want to feed through php or asp.
How do I make IE6 cache static images properly? How do I add custom response header for specific files/folders?
Hm, let met re-phrase it. I'm not sure it is caused by the bugs above. Actually, I tried appcmd to apply cacheControlMode/etc and it doesn't seem to work. As far as I remember, IE6 also does not cache for XMLHttpRequest calls? So, the biggest problem that I need to solve is:
in jQuery calendar, moving mouse over image buttons (prev/next) causes them to be reloaded-refreshed
in jQuery dialog, each dialog('open') causes images from theme (like header background) to be re-loaded/refreshed
etc
This link probably gives a better explanation: http://ajaxian.com/archives/internet-explorer-and-ajax-image-caching-woes
How do I solve this - that is, without feeding images through ASP.NET to setup headers?
Thanks everybody for listening, the trick with appcmd seems to work ;-) The problem was that I used jQuery theme from googleapis... which obviously was not affected by appcmd ;-) Moving theme to local folder did the trick. These are the commands:
\Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/images" -section:system.webServer/staticContent -clientCache.cacheControlMode:UseMaxAge
\Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/images" -section:system.webServer/staticContent -clientCache.cacheControlMaxAge:"01:00:00"
