  • How to test 500.html in (django) development env?

    - by lud0h
    I am using Django for a project and is already in production. In the production environment 500.html is rendered whenever a server error occurs. How do I test the rendering of 500.html in dev environment? Or how do I render 500.html in dev, if I turn-off debug I still get the errors and not 500.html background: I include some page elements based on a page and some are missing when 500.html is called and want to debug it in dev environment.

  • embedded web browser

    - by Ilya
    Hi, I'm looking for Linux embedded web browser, or preferably just a rendering object (it will not be used for actual browsing, just for displaying web based gui). The requirements are: Written in C (small footprint) Support Dynamic HTML Support Java script Minimum dependencies on the libraries (although i understand that it can not be completely standalone) No Dependency on X11 (i.e working with direct frame qui libraries) So far i only found Embedded Konqueror. Any suggestions are welcomed, commercial solutions are OK, but open source is preferable.

  • What's the best way to keep java app data stored redundantly in a file?

    - by Bijan
    If I have systems that are based on realtime data, how can I ensure that all the information that is current is redundantly stored in a file? So that when the program starts again, it uses this information to initialize itself back to where it was when it closed. I know of xstream and HSQLDB. but wasn't sure if this was the best option for data that needs to be a literal carbon copy.

  • How to make a ToolStripComboBox to fill all the space available on a ToolStrip?

    - by Ivan
    A ToolStripComboBox is placed after a ToolStripButton and is folowed by another one, which is right-aligned. How do I best set up the ToolStripComboBox to always adjust its length to fill all the space available between the preceeding and the folowing ToolStripButtons? In past I used to handle a parent resize event, calculate the new length to set based on neighboring elements coordinates and setting the new size. But now, as I am developing a new application, I wonder if there is no better way.

  • How can I create the XML::Simple data structure using a Perl XML SAX parser?

    - by DVK
    Summary: I am looking a fast XML parser (most likely a wrapper around some standard SAX parser) which will produce per-record data structure 100% identical to those produced by XML::Simple. Details: We have a large code infrastructure which depends on processing records one-by-one and expects the record to be a data structure in a format produced by XML::Simple since it always used XML::Simple since early Jurassic era. An example simple XML is: <root> <rec><f1>v1</f1><f2>v2</f2></rec> <rec><f1>v1b</f1><f2>v2b</f2></rec> <rec><f1>v1c</f1><f2>v2c</f2></rec> </root> And example rough code is: sub process_record { my ($obj, $record_hash) = @_; # do_stuff } my $records = XML::Simple->XMLin(@args)->{root}; foreach my $record (@$records) { $obj->process_record($record) }; As everyone knows XML::Simple is, well, simple. And more importantly, it is very slow and a memory hog—due to being a DOM parser and needing to build/store 100% of data in memory. So, it's not the best tool for parsing an XML file consisting of large amount of small records record-by-record. However, re-writing the entire code (which consist of large amount of "process_record"-like methods) to work with standard SAX parser seems like an big task not worth the resources, even at the cost of living with XML::Simple. I'm looking for an existing module which will probably be based on a SAX parser (or anything fast with small memory footprint) which can be used to produce $record hashrefs one by one based on the XML pictured above that can be passed to $obj->process_record($record) and be 100% identical to what XML::Simple's hashrefs would have been. I don't care much what the interface of the new module is; e.g whether I need to call next_record() or give it a callback coderef accepting a record.

  • Needed help with deleting rails cache

    - by WarDoGG
    I have been given a project of editing a website which is coded in RoR. However, the changes which i make in the view file is not visible immediately after a hard refresh but after 15-20 mins, the changes reflect. I am guessing this has something to do with the RoR caching system. Can someone please help me out ? The changes i made are purely HTML based like changing HTML attributes, filenames etc...

  • How do I format and apply rails methods to output of Ruport?

    - by Angela
    I am creating a report from Ruport and want to be able to take the grouping heading, in this case the ID for the class Email, and wrap a method around it and a link_to to link to the Email view based on the email_id: @table = ContactEmail.report_table(:all, :conditions => ['date_sent >= ? and date_sent <= ?', @monday, @friday]) @grouping = Grouping(@table, :by => "email_id") How do I do that? It feels as if I have little control over the output.

  • What are the advantages and disadvantages of a web site that contains a single page ?

    - by Misha Moroshko
    I would like to code a little web site that will contain several sections like "Home", "Gallery", "Contact Us", "FAQs", and so on. I thought to do this in one HTML by putting each section in a div and show only one div per time (using Javascript / jQuery), based on the chosen menu button. Alternatively, I could create a separate HTML page per section, and link these pages to the menu buttons. What are the advantages and disadvantages of these two methods ?

  • Perl: Compare and edit underlying structure in hash

    - by Mahfuzur Rahman Pallab
    I have a hash of complex structure and I want to perform a search and replace. The first hash is like the following: $VAR1 = { abc => { 123 => ["xx", "yy", "zy"], 456 => ["ab", "cd", "ef"] }, def => { 659 => ["wx", "yg", "kl"], 456 => ["as", "sd", "df"] }, mno => { 987 => ["lk", "dm", "sd"] }, } and I want to iteratively search for all '123'/'456' elements, and if a match is found, I need to do a comparison of the sublayer, i.e. of ['ab','cd','ef'] and ['as','sd','df'] and in this case, keep only the one with ['ab','cd','ef']. So the output will be as follows: $VAR1 = { abc => { 123 => ["xx", "yy", "zy"], 456 => ["ab", "cd", "ef"] }, def => { 659 => ["wx", "yg", "kl"] }, mno => { 987 => ["lk", "dm", "sd"] }, } So the deletion is based on the substructure, and not index. How can it be done? Thanks for the help!! Lets assume that I will declare the values to be kept, i.e. I will keep 456 = ["ab", "cd", "ef"] based on a predeclared value of ["ab", "cd", "ef"] and delete any other instance of 456 anywhere else. The search has to be for every key. so the code will go through the hash, first taking 123 = ["xx", "yy", "zy"] and compare it against itself throughout the rest of the hash, if no match is found, do nothing. If a match is found, like in the case of 456 = ["ab", "cd", "ef"], it will compare the two, and as I have said that in case of a match the one with ["ab", "cd", "ef"] would be kept, it will keep 456 = ["ab", "cd", "ef"] and discard any other instances of 456 anywhere else in the hash, i.e. it will delete 456 = ["as", "sd", "df"] in this case.

  • Slick: why would I save "Unit" to my database?

    - by alapeno
    I'm new to Scala and Slick and was surprised by something in the Slick documentation: The following primitive types are supported out of the box for JDBC-based databases in JdbcProfile ... Unit ... I don't get why this list contains Unit. From my understanding, Unit is similar to Java's void, something I neither can save to nor receive from my database. What is the intention behind it? edit: you can find it here.

  • Suggestions on documentation of a DB model when using Entity Framework 4

    - by Junior Ewing
    Any experiences on how to document Entity Framework 4 based Database projects? There is the Document and Summary properties on the Entities, but if we want to regenerate the model from the database at some point, it will be lost! Is there some way to map documentation data inside SQL to the Entities in the EDMX file so it is safe. Suggestions of other best practices? Ideally I want to be able to augo generate html/helpfile documentation from the DB when we deploy.

  • Port forwarding in C#/software possible? Isn't it only managed by the router?

    - by Rudi
    Isn't port forwarding managed by the router? Like, I've googled up some software applications that seem to port forward with great success, but it technically seems to be impossible. The packet must first go to the router. The router must forward it to the correct computer based on port forwarding rules. So how can a software application manage port forwarding if the packet must GO to the computer running this software application in the first place, meaning that port forwarding already is successful in the first place?

  • ExtJS data store for tree

    - by drewda
    I've got a basic ExtJS question, which I can't seem to resolve based on reading the docs and searching. Currently I have a TreePanel that loads JSON directly from a URL. I'm trying to separate the data from the view, so that I can also use that data to feed into an OpenLayers map (using GeoExt). How can I point a TreePanel to an Ext.data.Store rather than to a URL?

  • Modular GWT design concerns

    - by GlGuru
    Hi, I have a couple of questions regarding a modular GWT based application framework. I have some ideas about them but being new to the field of web development I feel they are far from ideal. I'd appreciate a few comments and suggestions in this regard. Here are my questions: I am developing a framework which will allow third parties to embed GWT applications into our website and do some communication with them using simple iFrame postMessage. All these third party modules are going to use our SDK which is also GWT based. The problem arises that even though all the modules will be using the same codebase there is going to be a massive overheard in the amount of duplicate Javascript code (i.e. our common SDK code base which is quite large) being downloaded on the client's machine. This is highly redundant and problematic, not only due to the sheer size of duplicate code but, also due to the fact that subsequent updates of the SDK would require the modules to be recompiled which is going to create a DLL hell kind of scenario in the long run. What is the best way of doing this kind of thing? Is there a way where I can have some static GWT code (i.e. the SDK) and the dynamic GWT module refers to it (even if lies on a different domain) and it all work happily? The other part of the problem lies in providing robust scripting front end to the SDK. At first it appears to be trivial since Javascript itself is a scripting language. However, I do not know how to load and call a piece of pure Javascript code at runtime? I am willing to put restrictions on the target Javascript (i.e. having a function main and unique namespace or something). Furthermore the Javascript will come as a string from a database and not as a full URL. If its doable in Javascript how does one get this right in GWT i.e. forcing the compiler to emit a certain function in the generated Javascript? This I believe can be lesser of a problem by having a stub Javascript with all the right requirements which just loads up a GWT generated Javascript. Is any of this possible at all? I generally hate to be this verbose but I hope to find a quick solution to the problem as its holding up my progress. I'd highly appreciate any comments, suggestions and experiences.
