| - | === getdata() === | ||
| - | This function retrieve brewer data using the interface describing in the [[codes:accessfunctions|access functions Section]]. This function accepts only an argument //params// which is a dictionary. Mandatory elements in //params// are the following strings: //user//, //password//, //berwerid// and //function//. The //function// element refers to the different functions described in the[[codes:accessfunctions|access functions Section]]. | + | === getDataList() === |
| + | |||
| + | This function retrieve a list of [[http://eubrewnet.aemet.es/dokuwiki/doku.php?id=devel:brewerpythonmodule#data_structures|dictionaries]] with data of the registered brewers at the RBCC-E database. Arguments are //berwerid//, //user//, //password//, //function//, //date1// and //date2//. If //date2// is omitted the function returns only data of the day //data1//. | ||
| + | |||
| + | The returned dictionaries structures depend on the //function// argument value: | ||

| **Example** | **Example** | ||
| - | params['user']='user' | + | import brewerjson |
| - | params['password']='password' | + | import datetime |
| - | params['function']='getDS' | + | |
| - | params['brewerid']='037' | + | d1=datetime.date(2014,10,01) |

| - | data=brewerjson.check_hg(params) | + | data=brewerjson.getDataList(185,'user,'password','DS',d1,d2) |
| - | In this example we retrieve data from the url: http://rbcce.aemet.es/eubrewnet/getdata/getDS?brewerid=037&date=2014-10-01 | ||
| - | This function returns different data structures depending on //function// parameter. | + | === writejson() === |
| + | This function save a list of [[http://eubrewnet.aemet.es/dokuwiki/doku.php?id=devel:brewerpythonmodule#data_structures|dictionaries]] to file. The values of 'gmt' and 'date' are transformed to strings. | ||
| - | === getDataList() === | + | **Example** |
| + | import brewerjson | ||
| + | import datetime | ||
| + | |||
| + | d1=datetime.date(2014,10,01) | ||
| + | d2=datetime.date(2014,10,02) | ||
| + | data=brewerjson.getDataList(185,'user,'password','DS',d1,d2) | ||
| + | brewerjson.getdata(data,'output.txt') | ||
| + | |||
| + | This function accepts two input parameters: //'data'// and //'file'//. | ||
| + | |||
| + | * //'data'// is a list of [[http://eubrewnet.aemet.es/dokuwiki/doku.php?id=devel:brewerpythonmodule#data_structures|dictionaries]]. | ||
| + | * //'file'// output file. | ||
| + | |||
| + | |||
| + | === readjson() === | ||
| + | |||
| + | This function read a file containing a list of [[http://eubrewnet.aemet.es/dokuwiki/doku.php?id=devel:brewerpythonmodule#data_structures|dictionaries]]. | ||
| + | |||
| + | **Example** | ||
| + | import brewerjson | ||
| + | import datetime | ||
