  • Rails rabl json format

    - by brabertaser1992
    I'm displaying data from my db in json format using rabl to parse it for android... My json looks like so: [ { "bank":{ "central_office_address":"ololo", "license":"12312312", "location_id":3, "name":"Pbank", "tax_number":"12312312", "year_of_foundation":1987 } }, { "bank":{ "central_office_address":"sdfsdf sdf", "license":"321312", "location_id":3, "name":"Bbank", "tax_number":"321321", "year_of_foundation":1999 } } ] I need my json in a format like: { "contacts": [ { "id": "c200", "name": "Ravi Tamada", "email": "[email protected]", "address": "xx-xx-xxxx,x - street, x - country", "gender" : "male", "phone": { "mobile": "+91 0000000000", "home": "00 000000", "office": "00 000000" } }, { "id": "c201", "name": "Johnny Depp", "email": "[email protected]", "address": "xx-xx-xxxx,x - street, x - country", "gender" : "male", "phone": { "mobile": "+91 0000000000", "home": "00 000000", "office": "00 000000" } } ] } Such data is normally parsed in java.... My rabl view: object @banks attributes :central_office_address, :license, :location_id, :name, :tax_number, :year_of_foundation How do I change its output to match the second example?

  • exporting html table multi line columns to excel multi line cells

    - by Passat
    I have a html table in a view MVC4 that I am sending to excel as output. Inside the view page I have some columns that have multiple lines that are built with forloops within the HTML. What's the best way to add the or \r\n so that excel renders it correctly? I have a table and inside I build each row looping thru a recordset. In each row I also loop thru different recordsets to populate columns within each row so that some of the columns may contain more than one value and they should show in different lines in the table that will export to excel.

    - by Aly
    Hi, I am using gnuplot to try and plot several lines but each have different x ranges. I am running the following script: # gnuplot script for 'omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat' plot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:2 with lines title '1' replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:3 with lines title '2' replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:4 with lines title '3' replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:5 with lines title '4' replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:6 with lines title '5' replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:7 with lines title '6' replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:8 with lines title '7' set terminal png size 800,600 set output "omar_vs_everyone-EVONLY.png" replot and the .dat file is just a file with columns such as: 1 0.5 0.5 0.1 2 0.6 1.3 0.8 3 0.7 0.32 4 0.7 0.35 5 1.3 4.32 6 1.67 notice that the columns have different lengths as each line has different x ranges. The problem I have is that it plots funny as shown below:

  • Python list comprehension overriding value

    - by Joschua
    Hi, folks have a look at the following piece of code, which shows a list comprehension.. >>> i = 6 >>> s = [i * i for i in range(100)] >>> print(i) When you execute the code example in Python 2.6 it prints 99, but when you execute it in Python 3.x it prints 6. What were the reason for changing the behaviour and why is the output 6 in Python 3.x? Thank you in advance!

  • Errors/Warnings/Debug Info no longer appears in Debug Console

    - by Alex L
    Hi Guys: This one is driving me crazy. When I run my App and open the Debug Console there is nothing there! Nope, not even the output from my NSLog statements. Before I would see a bunch of debug information starting with [Session Started ...] and ending with 'Terminating in response to SpringBoard's termination'. The Status Bar at the bottom of the Console says my App was successfully launched. Even Errors and Warnings from my code no longer appear. How do I get this to show up again? Any help would be greatly appreciated.

  • PHP: Regular Expression to get a URL from a string

    - by Matthew Iselin
    I'm working on some PHP code which takes input from various sources and needs to find the URLs and save them somewhere. The kind of input that needs to be handled is as follows: http://www.youtube.com/watch?v=IY2j_GPIqRA Try google: http://google.com! (note exclamation mark is not part of the URL) Is http://somesite.com/ down for anyone else? Output: http://www.youtube.com/watch?v=IY2j_GPIqRA http://google.com http://somesite.com/ I've already borrowed one regular expression from the internet which works, but unfortunately wipes the query string out - not good! Any help putting together a regular expression, or perhaps another solution to this problem, would be appreciated.

    - by geoff
    I am trying to use Beyond Compare for Visual Diff in TortoiseHg. eg Right click on a modified file in explorer and select Visual Diff from TortoiseHg context menu...

  • Help me write a nicer SQL query in Rails

    - by Sainath Mallidi
    Hi, I am trying to write an SQL query to update some of the attributes that are regularly pulled from source. the output will be a text file with the following fields: author, title, date, popularity I have two tables to update one is the author information and the other is popularity table. And the Author Active Record object has one popularity. Currently I'm doing it like this.\ arr.each { |x| x = x.split(" ") results = Author.find_by_sql("SELECT authors.id FROM authors, priorities WHERE authors.id=popularity.authors_id AND authors.author = x[0]") results[0].popularity.update_attribute("popularity", x[3]) I need two tables because the popularity keeps changing, and I need only the top 1000 popular ones, but I still need to keep the previously popular ones also. Is there any nicer way to do this, instead of one query for every new object. Thanks.

  • Vim, how to scroll to bottom of a named buffer

    - by Gavin Black
    I have a vim-script which splits output to a new window, using the following command: below split +view foo I've been trying to find a way from an arbitrary buffer to scroll to the bottom of foo, or a setting to keep it defaulted to showing the bottom lines of the buffer. I'm doing most of this inside of a python block of vim script. So I have something like: python << endpython import vim import time import thread import sys def myfunction(string,sleeptime,*args): outpWindow = vim.current.window while 1: outpWindow.buffer.append("BAR") #vim.command("SCROLL TO BOTTOM OF foo") time.sleep(sleeptime) #sleep for a specified amount of time. vim.command('below split +view foo') thread.start_new_thread(myfunction,("Thread No:1",2)) endpython And need to find something to put in for vim.command("SCROLL TO BOTTOM of foo") line

  • Perl, dereference array of references

    - by Mike
    In the following Perl code, I would expect to be referencing an array reference inside an array #!/usr/bin/perl use strict; use warnings; my @a=([1,2],[3,4]); my @b = @$a[0]; print $b[0]; However it doesn't seem to work. I would expect it to output 1. @a is an array of references @b is $a[1] dereferenced (I think) So what's the problem?

  • Any experience with the Deliverance system ?

    - by e-satis
    My new boss went to a speech where Deliverance, a kind of proxy allowing to add skin to any html output on the fly, was presented. He decided to use it right after that, no matter how young it is. More here : http://www.openplans.org/projects/deliverance/introduction In theory, the system sounds great when you want a newbie to tweak your plone theme without having to teach him all the complex mechanisms behind the zope products. And apply the same theme on a Drupal web site in one row. But I don't believe in theory, and would like to know if anybody tried this out in the real world :-)

    How do I revert from my current state to a snapshot made on a certain commit?

    I have this Perl code: foreach (@tmp_cycledef) { chomp; my ($cycle_code, $close_day, $first_date) = split(/\|/, $_,3); $cycle_code =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; $close_day =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; $first_date =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; #print "$cycle_code, $close_day, $first_date\n"; $cycledef{$cycle_code} = [ $close_day, split(/-/,$first_date) ]; } The value of tmp_cycledef comes from output of an SQL query: select cycle_code,cycle_close_day,to_char(cycle_first_date,'YYYY-MM-DD') from cycle_definition d order by cycle_code; What exactly is happening inside the for loop?

  • printing out posts

    - by yCalleecharan
    Hi, I'm using the Firefox browser and trying to print out my posts (and replies). The pdf output doesn't include the comments in the posts. How to make sure that everything which is on the page gets printed? Same goes for codes for which are in a window. Only the visible part of the code gets printed. These are not programming questions :) but I hope that someone can suggest how to get proper printouts of the posts. Thanks a lot...

  • BeautifulSoup Parser Confusion - HTML

    - by lyngbym
    I'm trying to scrape some content off another site and I'm not sure why BeautifulSoup is producing this output. It is only finding a blank space inside the match, but the real HTML contains a large amount of markup. I apologize if this is something stupid on my part. I'm new to python. Here's my code: import sys import os import mechanize import re from BeautifulSoup import BeautifulSoup def scrape_trails(BASE_URL, data): #Get the trail names soup = BeautifulSoup(data) sitesDiv = soup.findAll("div", attrs={"id" : "sitesDiv"}) print sitesDiv def main(): BASE_URL = "http://www.dnr.state.mn.us/skiing/skipass/list.html" br = mechanize.Browser() data = br.open(BASE_URL).get_data() links = scrape_trails(BASE_URL, data) if __name__ == '__main__': main() If you follow that URL you can see the sitesDiv contains a lot of markup. I'm not sure if I'm doing something wrong or if this is just malformed markup that the script can't handle. Thanks!

  • Modifiers in Makefile rule's dependency list

    - by gnu_maker
    The problem is fairly simple. I am trying to write a rule, that given the name of the required file will be able to tailor its dependencies. Let's say I have two programs: calc_foo and calc_bar and they generate a file with output dependent on the parameter. My target would have a name 'target_*_*'; for example, 'target_foo_1' would be generated by running './calc_foo 1'. The question is, how to write a makefile that would generate outputs of the two programs for a range of parameters?

  • What to do if exec() fails?

    - by Grigory
    Let's suppose we have a code doing something like this: int pipes[2]; pipe(pipes); pid_t p = fork(); if(0 == p) { dup2(pipes[1], STDOUT_FILENO); execv("/path/to/my/program", NULL); ... } else { //... parent process stuff } As you can see, it's creating a pipe, forking and using the pipe to read the child's output (I can't use popen here, because I also need the PID of the child process for other purposes). Question is, what should happen if in the above code, execv fails? Should I call exit() or abort()? As far as I know, those functions close the open file descriptors. Since fork-ed process inherits the parent's file descriptors, does it mean that the file descriptors used by the parent process will become unusable?

  • PHP: creating a smooth edged circle, image or font?

    - by Chad Whitaker
    I'm making a PHP image script that will create circles at a given radius. I used: <?php imagefilledellipse ( $image, $cx, $cy, $w, $h, $color ); ?> but hate the rough edges it produces. So I was thinking of making or using a circle font that I will output using: <?php imagettftext ( $image, $size, $angle, $x, $y, $color, 'fontfile.ttf', $text ); ?> So that the font will produce a circle that has a smooth edge. My problem is making the "font size" match the "radius size". Any ideas? Or maybe a PHP class that will produce a smooth edge on a circle would be great! Thank you.

  • Is there a way to convert code to a string and vice versa in Python?

    - by Dragos Toader
    The original question was: Is there a way to declare macros in Python as they are declared in C: #define OBJWITHSIZE(_x) (sizeof _x)/(sizeof _x[0]) Here's what I'm trying to find out: Is there a way to avoid code duplication in Python? In one part of a program I'm writing, I have a function: def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) In another part, I've got this code embedded in a string that will later be output to a python file that will itself be run: """ def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) """ How can I build a "macro" that will avoid this duplication?
