python - Pythonic way to create dictionary from bottom level of nested dictionary -

-

i have dictionary contains nested dictionaries, this:

example_dict = {                 "test1": "string here",                 "test2": "another string",                 "test3": {                         "test4": 25,                         "test5": {                                   "test7": "very nested."                         },                         "test6": "yep, string"                 }, }

assuming keys nested within unique, there pythonic way take dictionary , obtain 'bottom' level of keys , values?

by mean going recursive dictionary , obtaining key:value pairs value isn't dictionary (but still capturing key:value pairs within fulfil critera)? above following returned:

resulting_dict = {                 "test1": "string here",                 "test2": "another string",                 "test4": 25,                 "test7": "very nested.",                 "test6": "yep, string" }

with bit of recursion it's simple do:

example_dict = {     "test1": "string here",     "test2": "another string",     "test3": {         "test4": 25,         "test5": {             "test7": "very nested."         },         "test6": "yep, string"     }, }   def flatten(dictionary):     output = dict()     k, v in dictionary.items():         if isinstance(v, dict):             output.update(flatten(v))         else:             output[k] = v      return output  resulting_dict = flatten(example_dict)

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
