  • Passing hash as values in hidden_field_tag

    - by funkymunky
    I am trying to pass some filters in my params through a form like so: hidden_field_tag "filters", params[:filters] For some reason the params get changed in the next page. For example, if params[:filters] used to be... "filters"={"name_like_any"=["apple"]} [1] ...it gets changed to... "filters"="{\"name_like_any\"=[\"apple\"]}" [2] note the extra quotations and backslashes in [2] when compared to [1]. Any ideas? I'm attempting to use this with searchlogic for some filtering, but I need it to persist when I change change objects in forms. I would prefer not to have to store it in session.

  • Inheriting list item permissions via permissions on lookup field item

    - by Dan Sydner
    Say you have two lists in Sharepoint, let's call them "house" and "region". Each house is assigned to a region via a lookup field. List item permissions are set on regions. Now I want the users only to only see the houses which belong to the regions they have read access to. I reckon it should be relatively simple I see no easy way of doing this. Am I over looking something.

  • How do I print out objects in an array in python?

    - by Jonathan
    I'm writing a code which performs a k-means clustering on a set of data. I'm actually using the code from a book called collective intelligence by O'Reilly. Everything works, but in his code he uses the command line and i want to write everything in notepad++. As a reference his line is >>>kclust=clusters.kcluster(data,k=10) >>>[rownames[r] for r in k[0]] Here is my code: from PIL import Image,ImageDraw def readfile(filename): lines=[line for line in file(filename)] # First line is the column titles colnames=lines[0].strip( ).split('\t')[1:] rownames=[] data=[] for line in lines[1:]: p=line.strip( ).split('\t') # First column in each row is the rowname rownames.append(p[0]) # The data for this row is the remainder of the row data.append([float(x) for x in p[1:]]) return rownames,colnames,data from math import sqrt def pearson(v1,v2): # Simple sums sum1=sum(v1) sum2=sum(v2) # Sums of the squares sum1Sq=sum([pow(v,2) for v in v1]) sum2Sq=sum([pow(v,2) for v in v2]) # Sum of the products pSum=sum([v1[i]*v2[i] for i in range(len(v1))]) # Calculate r (Pearson score) num=pSum-(sum1*sum2/len(v1)) den=sqrt((sum1Sq-pow(sum1,2)/len(v1))*(sum2Sq-pow(sum2,2)/len(v1))) if den==0: return 0 return 1.0-num/den class bicluster: def __init__(self,vec,left=None,right=None,distance=0.0,id=None): self.left=left self.right=right self.vec=vec self.id=id self.distance=distance def hcluster(rows,distance=pearson): distances={} currentclustid=-1 # Clusters are initially just the rows clust=[bicluster(rows[i],id=i) for i in range(len(rows))] while len(clust)>1: lowestpair=(0,1) closest=distance(clust[0].vec,clust[1].vec) # loop through every pair looking for the smallest distance for i in range(len(clust)): for j in range(i+1,len(clust)): # distances is the cache of distance calculations if (clust[i].id,clust[j].id) not in distances: distances[(clust[i].id,clust[j].id)]=distance(clust[i].vec,clust[j].vec) #print 'i' #print i #print #print 'j' #print j #print d=distances[(clust[i].id,clust[j].id)] if d<closest: closest=d lowestpair=(i,j) # calculate the average of the two clusters mergevec=[ (clust[lowestpair[0]].vec[i]+clust[lowestpair[1]].vec[i])/2.0 for i in range(len(clust[0].vec))] # create the new cluster newcluster=bicluster(mergevec,left=clust[lowestpair[0]], right=clust[lowestpair[1]], distance=closest,id=currentclustid) # cluster ids that weren't in the original set are negative currentclustid-=1 del clust[lowestpair[1]] del clust[lowestpair[0]] clust.append(newcluster) return clust[0] def kcluster(rows,distance=pearson,k=4): # Determine the minimum and maximum values for each point ranges=[(min([row[i] for row in rows]),max([row[i] for row in rows])) for i in range(len(rows[0]))] # Create k randomly placed centroids clusters=[[random.random( )*(ranges[i][1]-ranges[i][0])+ranges[i][0] for i in range(len(rows[0]))] for j in range(k)] lastmatches=None for t in range(100): print 'Iteration %d' % t bestmatches=[[] for i in range(k)] # Find which centroid is the closest for each row for j in range(len(rows)): row=rows[j] bestmatch=0 for i in range(k): d=distance(clusters[i],row) if d<distance(clusters[bestmatch],row): bestmatch=i bestmatches[bestmatch].append(j) # If the results are the same as last time, this is complete if bestmatches==lastmatches: break lastmatches=bestmatches # Move the centroids to the average of their members for i in range(k): avgs=[0.0]*len(rows[0]) if len(bestmatches[i])>0: for rowid in bestmatches[i]: for m in range(len(rows[rowid])): avgs[m]+=rows[rowid][m] for j in range(len(avgs)): avgs[j]/=len(bestmatches[i]) clusters[i]=avgs return bestmatches

  • How to update the filename of a Django's FileField instance ?

    - by pierre-guillaume-degans
    Hello, Here a simple django model: class SomeModel(models.Model): title = models.CharField(max_length=100) video = models.FileField(upload_to='video') I would like to save any instance so that the video's file name would be a valid file name of the title. For example, in the admin interface, I load a new instance with title "Lorem ipsum" and a video called "video.avi". The copy of the file on the server should be "Lorem Ipsum.avi" (or "Lorem_Ipsum.avi"). Thank you :)

  • ActionScript Tweening Matrix Transform (big problem)

    - by TheDarkIn1978
    i'm attempting to tween the position and angle of a sprite. if i call the functions without tweening, to appear in one step, it's properly set at the correct coordinates and angle. however, tweening it makes it all go crazy. i'm using an rotateAroundInternalPoint matrix, and assume tweening this along with coordinate positions is messing up the results. works fine (without tweening): public function curl():void { imageWidth = 400; imageHeight = 600; parameters.distance = 0.5; parameters.angle = 45; backCanvas.x = imageWidth - imageHeight * parameters.distance; backCanvas.y = imageHeight - imageHeight * parameters.distance; var internalPointMatrix:Matrix = backCanvas.transform.matrix; MatrixTransformer.rotateAroundInternalPoint(internalPointMatrix, backCanvas.width * parameters.distance, 0, parameters.angle); backCanvas.transform.matrix = internalPointMatrix; } doesn't work properly (with tweening): public function curlUp():void { imageWidth = 400; imageHeight = 600; parameters.distance = 0.5; parameters.angle = 45; distanceTween = new Tween(parameters, "distance", None.easeNone, 0, distance, 1, true); angleTween = new Tween(parameters, "angle", None.easeNone, 0, angle, 1, true); angleTween.addEventListener(TweenEvent.MOTION_CHANGE, animateCurl); } private function animateCurl(evt:TweenEvent):void { backCanvas.x = imageWidth - imageHeight * parameters.distance; backCanvas.y = imageHeight - imageHeight * parameters.distance; var internalPointMatrix:Matrix = backCanvas.transform.matrix; MatrixTransformer.rotateAroundInternalPoint(internalPointMatrix, backCanvas.width * parameters.distance, 0, parameters.angle - previousAngle); backCanvas.transform.matrix = internalPointMatrix; previousAngle = parameters.angle; } in order for the angle to tween properly, i had to add a variable that would track it's last angle setting and subtract it from the new one. however, i still can not get this tween to return the same end position and angle as is without tweening. i've been stuck on this problem for a day now, so any help would be greatly appreciated.

  • Mandatory Embedded schema field not throwing excepiton when empty in SDL Tridion 2011

    - by user1733557
    I am pulling back to the basic schema questions in Tridion 2011. I have an embedded schema with three optional fields and I referred this schema in a content schema and marked it as mandatory. When I create a component and save it without entering data to this mandatory field; CME is not throwing any exception and proceeds with saving. Please let me know if there are any patches to resolve this issue. Thanks in advance.

  • Matching day in datetime field from sqlite

    - by 99miles
    In Ruby on Rails I'm doing something like: Appointment.find( :first, :conditions => "staff_id = #{staff_id} AND datetimefield = #{datetime}") ... where datetimefield is of course, a datetime field. But, I only want rows where the date is equal to a given day, say 2/12/2011. I don't care about the time. What's an easy way to do this? Thanks!

  • Can Fluent nhibernate's automapper be configured to handle private readonly backing fields?

    - by Mark Rogers
    I like private readonly backing fields because some objects are mostly read-only after creation, and for collections, which rarely need to be set wholesale (instead using collection methods to modify the collection). For example: public class BuildingType : DomainEntity { /* rest of class */ public IEnumerable<ActionType> ActionsGranted { get { return _actionsGranted; } } private readonly IList<ActionType> _actionsGranted = new List<ActionType>(); private readonly Image _buildingTile; public virtual Image BuildingTile { get { return _buildingTile; } } } But as far as I remember fluent-nhibernate's automapper never had a solution for private readonly backing fields, I'm wondering if that's changed in the last few months. So here's my question: How do I configure automapper or create an automapping convention to map private readonly backing fields?

  • Wordpress Custom Field

    I wanted to use the custom field for wordpress to have a different header banner for my site here is my code: <?php get_header(); ?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <div id="BodyWrap"> <!--MAIN CONT--> <div id="mainCont"> <?php get_sidebar(); ?> <div id="rotateBanner"><?php // check for image $image = get_post_meta($post->ID, 'image', $single = true);?> <img class="mainImg" src="<?php bloginfo(template_url); echo $image; ?>" alt=""/> </div> <div id="mainCopy"> <div id="content"> <h2><?php single_post_title(); ?></h2> <?php the_content('<p class="serif">Read the rest of this page &raquo;</p>'); ?> <?php wp_link_pages(array('before' => '<p><strong>Pages:</strong> ', 'after' => '</p>', 'next_or_number' => 'number')); ?> </div> </div> </div> </div> <?php endwhile; endif; ?> <?php get_footer(); ?> Now the code renders but for some reason it only renders the img path as: <img alt="" src="http://www.testground.idghosting.com/philcom/wp-content/themes/phil"/> here is the demosite in the custom field I put this: image For the value I put this: /images/sampleHead.png

  • How to enforce unique-field validation in MVC

    - by xandy
    I am in the way building some MVC Application and I really love the Data Annotations support in MVC. The build in support is good enough to enforce simple validation checkup. I wonder, how to implement unique-field validation using custom data-annotation ? For example, I have a view model that need the user to register a new login name, is there way to check (using Model.IsValid) whether the name is not existed before calling the db submit?
