How to keep Flask use_reloader working while Debug is False? - ajax

my Flask app was launching twice , so I have tried "debug=False" , but this is preventing auto reload while i am changing ajax code .
so i am starting my app like this
if name == 'main':
app.run(debug=False, use_reloader=True ,host='0.0.0.0', port=4002)
but auto_reload is not working

Official Flask Documentation says:
debug must be True (i.e., exceptions must be caught) in order for the other two options (i.e use_reloader and use_debugger) to have any value.
So that means, with debug=False, use_reloader ain't gonna have any value to work with and as a result, you won't get what you want.

Cypress: Switching from cy.route() to cy.intercept()

It seems that most people I read about experence zero trouble with this. I, on the other hand, have a test suite which someone else wrote, in which I'm trying to replace route() with intercept(). The API intercepts are done to handle button clicks etc., and about 99.9% percent of them fails if I just replace it. So, there's obviously some syntax in/use of intercept() I've not found a description for.
Example:
This works:
cy.route('POST', getApiPrefix() + '/prosjektfinansiering/'+ pfId +'/eiendom', result);
This does not work. The button click is not executed:
cy.intercept('POST', getApiPrefix() + '/prosjektfinansiering/'+ pfId +'/eiendom', result);
I've tried adding '**' in front of "/prosjekt...", and I've tried removing 'POST', with no luck.
Any ideas? I'll gladly post more info if necessary.
UPDATE:
Futher attempts:
Getting some hints here and there, it seems that this is a more correct way of using intercept():
return cy.intercept('POST', getApiPrefix() + '/prosjektfinansiering/'+ pfId +'/eiendom', {
body: result
});
This doesn't work, either.
The variables result in these examples is an object describing what is sent back to the frontend of the POST-request in the route matches the api path.
For troubleshooting, I can see that when using intercept(), there is ONE route that is not working when using intercept (the bottom one in the picture). However, I cannot for the life of me see why, and how the route match can be written differently?
Most likely, you're mixing the old use of cy.route() and cy.server(). In my experience, those two won't work well together. It's easier when you're starting fresh with just cy.intercept().
Your update is correct too; You have to encapsulate the return value you want mocked in {body: value}.
from what I am seeing in your circled screenshot, the API is not called after you try to intercept it. (the count under # column is -)
You need to track when the API is to be called and ensure you intercept before the call is made. Cypres can help you with this. You can go through the run steps in the cypress window.
You could also share this if you don't mind.
If you are 100% certain the button makes the call. Steps should be:
cy.intercept()
cy.get('button').click()
In the cypress window, right after the click, you should see the API being called.

why scrapy won't load any of my pipelines?

ok, so Im using Scrapy for some basic web scraping and its working fine on scraping part! when get some output using feed export something like -o output.csv wont do anything, it will make an empty file but nothing else.
after a period of confusion I couldn't make it work so i've decided to use a pipeline to write some custom method of exporting. but now the problem is even though the application is working fine... its just not load the pipelines. not any single one of them is not running and there is no error.
this is my settings.py where I put the option to load them:
ITEM_PIPELINES = {
'fbcrawl.pipelines.CsvExporterPipeline': 300
}
and this is my CsvExporterPipeline class inside pipelines.py:
class CsvExporterPipeline(object):
def process_item(self, item, spider):
print('\n' * 2)
print(item)
print('\n' * 2)
return item
and its not gonna run neither of these 3 prints wont run at all.
I want to know how can I have my pipelines loaded and working?
UPDATE: i forgot to mention that im trying to run this code... so the spider is mentioned here:
https://github.com/rugantio/fbcrawl
Are you sure BOT_NAME in settings.py is set at fbcrawl ?
And what is the code of your spider ?

Nativescript angular detect first run

Is there a way to detect first application run (on new build)? I can think of some custom solutions like a config file where I would write some flag after first run, but this wouldn't help me much. I'd like to show loading screen on first run, which would be different from the runs after.
In your imports:
import * as appSettings from "application-settings";
Then use:
appSettings.getBoolean("isFirst", true); - checks if its the first time loading up. If it is, "isFirst" won't exist and will therefore return true as , true) sets the return to true if the value isn't there.
You can then use:
appSettings.setBoolean("isFirst", false); - use this after logging in to set the value of "isFirst" for the next time

Turn off FireFox driver refresh POST warning

I have inherited some GEB tests that are testing logging into a site (and various error cases/validation warnings).
The test runs through some validation failures and then it attempts to re-navigate to the same page (just to refresh the page/dom) and attempts a valid login. Using GEB's to() method, it detects that you are attempting to navigate to the page you are on, it just calls refresh - the problem here is that attempts to refresh the last POST request, and the driver displays the
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier"
message - as the test is not expecting this popup, it hangs and the tests timeout.
Is there a way to turn off these warnings in Firefox webdriver? or to auto-ignore/accept them via Selenium or GEB?
GEB Version: 0.9.2,
Selenium Version: 2.39.0
(Also tried with minor version above: 0.9.3 & 2.40.0)
Caveats:
I know about the POST/Re-direct/GET pattern - but am not at liberty to change the application code in this case
The warning message only causes an issue intermittently (maybe 1 in 5 times) - I have put this down to speed/race conditions whereby the test completes the next actions before the message appears - I know a possible solution is to update tests to wait for message to appear and then accept, but my question is, is there a global setting that can just avoid these being triggered/displayed?
That refresh() is there to work around an issue with IE driver which ignores calls to driver.get() with the same url as the current one.
Instead of monkey patching Browser class (which might bite you somewhere down the line or might not) I would change the url of your login page class. You might for example add an insignificant query string - I think that simply a ? at the end should suffice. The driver.currentUrl == newUrl condition will evaluate to false and you will not see that popup anymore.
If I understand you issue properly this might help. In Groovy you can modify a class on the fly.
We use Spock with Geb and I placed this in a Super class which all Spock Spec inherit from. Eg: QSpec extends GebSpec.
It is the original method slightly modified with the original code commented out so you know what has been changed. I use this technique in several required places to alter Geb behaviour.
static {
Browser.metaClass.go = { Map params, String url ->
def newUrl = calculateUri(url, params)
// if (driver.currentUrl == newUrl) {
// driver.navigate().refresh()
// } else {
// driver.get(newUrl)
// }
driver.get(newUrl)
if (!page) {
page(Page)
}
}
}

Logging an onFailure inError in WebOS

An onFailure handler in webOS has an argument inError. I tried printing it using: console.log("error: " + inError);, but the result is only: error: [object Object]*** (app/assistants/main-assistant.js:26), which isn't much use. How can I log something more useful instead?
Update:
Ares generates: alarm1Failure: function(inSender, inError) {}. However, the error is contained as the errorText property of the first object and the second object is the request
I would use the interactive debugger at:
http://ares.palm.com/AresDebug/
Connect your device and run your app. Put your app name in the 'Script Filter' box and click get scripts.
Now use the 'Available Scripts' pull down to find your assembly.
You can set breakpoints (click on line numbers to the left) and inspect variables using the lower left pane and '>' prompt.
Be sure to use Chrome or Safari as it will not work with IE.
There is also a logger at:
http://ares.palm.com/AresLog/
if you don't want to use the debugger, then you probably should know something about the inError object getting returned to you. In this case I assume the onFailure comes from a Protocol function's callback, so try looking in the Protocol documentation to see what information the error object should contain.
Also for any logging purposes don't forget about the imensely useful function
JSON.stringify(obj)
It will take an object and return a JSON representation that you can log so you can see all the properties at once.
