  • Adding a button or link to an inline in Django admin

    - by Lexo
    Hello, I have created the following django models: class Entry(SiteObject): parent = models.ForeignKey(Blog, related_name="entries") content = models.TextField(help_text = "The Content of the blog post") class EntryImage(models.Model): entry = models.ForeignKey(Entry, related_name="entryimages") imagewidth = models.PositiveIntegerField(editable=False,) imageheight = models.PositiveIntegerField(editable=False,) image_file = ImageWithThumbnailsField( #from sorl-thumbnail. Basically a wrapper for an ImageField that generates a thumbnail. upload_to="images/blogs", height_field="imageheight", width_field="imagewidth", help_text = "Select an image to upload.", thumbnail={'size': (360,720)}, generate_on_save=True, ) The EntryImage class shows up as an inline in the admin page for Entry. What I'd like to do is place a link or a button beside each of these inlines that does the following: Save the EntryImage Append <Image x> to the content of the Entry, where x is the number of the EntryImage. This will be replaced by the image's thumbnail using a template filter. Save the Entry Return to editing the Entry I have looked into this, but I just can't wrap my head around where I'm supposed to add this button or link. Has anyone else tried something similar? I've got JQuery available, since I'm using WYMEditor for the content field of the Entry class. Would this help? Thanks in advance, Lexo

  • managing html rich text selections

    - by swami
    Hi, I am writing a component for a web app which will display some html, and let me capture and manipulate the selection boundaries (of the text selected by the user). I have done this successfully (for Mozilla) with a simple div element using window.getSelection(). However, the browser selection API is different for IE. If I were to use a textarea instead (for interacting with the selection api), is there a uniform API across the browsers? Then I would need to overlay a DIV on top of this to display the styled text, and presumably I'd need to manage the cursor etc... Basically I want a rich text editor - but without editing. Does anyone have any advice on the best way to go about this, which is quick, simple and cross browser compatible. I don't want to spend ages reinventing the wheel... (If anyone's interested - this is for an online xml editor. I capture the users selection on a html version of the xml doc and then send the selection offsets info to the server, where the real xml doc gets marked up). Kind Regards Swami

  • Flex datagrid headerColor style is not working....

    - by Jerry
    Hello guys. I am trying to change the datagrid header color by editing headerColor style. I could change the font size, font family...etc except the headerColor. Would someone help me about it?

  • Django: How to dynamically add tag field to third party apps without touching app's source code

    - by Chris Lawlor
    Scenario: large project with many third party apps. Want to add tagging to those apps without having to modify the apps' source. My first thought was to first specify a list of models in settings.py (like ['appname.modelname',], and call django-tagging's register function on each of them. The register function adds a TagField and a custom manager to the specified model. The problem with that approach is that the function needs to run BEFORE the DB schema is generated. I tried running the register function directly in settings.py, but I need django.db.models.get_model to get the actual model reference from only a string, and I can't seem to import that from settings.py - no matter what I try I get an ImportError. The tagging.register function imports OK however. So I changed tactics and wrote a custom management command in an otherwise empty app. The problem there is that the only signal which hooks into syncdb is post_syncdb which is useless to me since it fires after the DB schema has been generated. The only other approach I can think of at the moment is to generate and run a 'south' like database schema migration. This seems more like a hack than a solution. This seems like it should be a pretty common need, but I haven't been able to find a clean solution. So my question is: Is it possible to dynamically add fields to a model BEFORE the schema is generated, but more specifically, is it possible to add tagging to a third party model without editing it's source. To clarify, I know it is possible to create and store Tags without having a TagField on the model, but there is a major flaw in that approach in that it is difficult to simultaneously create and tag a new model.

  • How to have an iCalendar (RFC 2445) repeat YEARLY with duration

    - by Todd Brooks
    I have been unsuccessful in formulating a RRULE that would allow an event as shown below: Repeats YEARLY, from first Sunday of April to last day of May, occuring on Monday, Wednesday and Friday, until forever. FREQ=YEARLY;BYMONTH=4;BYDAY=SU (gives me the first Sunday of April repeating yearly) and FREQ=YEARLY;BYMONTH=5;BYMONTHDAY=-1 (gives me the last day of May repeating yearly) But I can't figure out how to have the event repeat yearly between those dates for Monday, Wednesday and Friday. Suggestions? Update: Comments don't have enough space to respond to Chris' answer, so I am editing the question with further information. Unfortunately, no. I don't know if it is the DDay.iCal library I'm using, or what, but that doesn't work either. I've found that the date start can't be an ordinal date (first Sunday, etc.)..it has to be a specific date, which makes it difficult for my requirements. Even using multiple RRULE's it doesn't seem to work: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//DDay.iCal//NONSGML ddaysoftware.com//EN BEGIN:VEVENT CREATED:20090717T033307Z DTSTAMP:20090717T033307Z DTSTART:20090101T000000 RRULE:FREQ=YEARLY;WKST=SU;BYDAY=MO,WE,FR;BYMONTH=4,5 RRULE:FREQ=YEARLY;WKST=SU;BYDAY=1SU;BYMONTH=4 RRULE:FREQ=YEARLY;WKST=SU;BYMONTH=5;BYMONTHDAY=-1 SEQUENCE:0 UID:352ed9d4-04d0-4f06-a094-fab7165e5c74 END:VEVENT END:VCALENDAR That looks right on the face (I'm even starting the event on 1/1/2009), but when I start testing whether certain days are valid, I get incorrect results. For example, 4/1/2009 12:00:00 AM = True // Should be False 4/6/2009 12:00:00 AM = True 4/7/2009 12:00:00 AM = False 4/8/2009 12:00:00 AM = True 5/1/2009 12:00:00 AM = True 5/2/2009 12:00:00 AM = False 5/29/2009 12:00:00 AM = True 5/31/2009 12:00:00 AM = True // Should be False 6/1/2009 12:00:00 AM = False I'm using Douglas Day's DDay.iCal software, but I don't think it is a bug in that library. I think this might be a limitation in iCalendar (RFC 2445). Thoughts?

  • Properly design a code editor application

    - by Hemaulo
    I'm working on personal project which is basically a code editor. Imagine standard File menu with menu items New, Open, Save, Save As, Save All, Close, Close All. I'm stuck with proper design. Currently I have: A Document class which represents a document - code editing control, respective tab in tab bar and various properties such as Caption, Filename, IsModified etc. A Documents class which represents all open documents. Contains methods like New, Open(FileName), ... The problem is that I can't figure out which class / menu command is responsible for which tasks. For example, with File-New menu command is simple - call Documents.New and that's it. But what for File-Open? The Documents.Open method expects filename as a parameter. So before calling this method I need to open an file selection dialog, let user select files and for each file call Documents.Open(FileName). Where is best place for this supporting code, in menu command, rewrite Documents.Open and put it there? The same with Save actions. Which is responsible for saving? Is it Documents class which uses Document.Editor.SaveToFile(FileName) or better create Save method in Document class? Somewhere in the middle also need to ask user if he wants to save current document... I'm stuck. Any ideas? Edited: The programming language is Delphi.

  • How to syntax-highlight XML in CDATA elements in Vim?

    - by Jim Hurne
    Vim's syntax highlighting for XML/XSL is great, except it turns off all syntax highlighting in CDATA regions. Is there a way to turn on syntax highlighting on in CDATA regions? At work, we have a lot of XSL code embedded within other XML documents. It would be great if I could get all of the goodness of XML editing for the embedded XSL code as well without having to temporarily remove the CDATA tags, or copy the CDATA content into a temporary file. Example: <root> <someTag><![CDATA[ <xsl:template match="/"> <!-- XSL content here --> </xsl:template> ]]> </someTag> </root> Note that the name of the tag (in the example, someTag) containing the content could be anything. We also sometimes embed Javascript inside CDATA regions as well, and again, it would be nice to turn on Javascript syntax highlighting for those regions. Again, the tag the data is embedded in is usually arbitrary and can be anything.

  • Is this a bug in plist or Xcode?

    - by Pedro
    G'day All If you create a date item in the plist editor of Xcode or Apple's standalone plist editor you get something of the form <date>2010-05-29T10:30:00Z</date> which is a nice well formed ISO date at UTC (indicated by the "Z"). Because I'm in timezone UTC +10 when that's read into my app & then displayed I get 8:30 PM out, still good. However if that is a time in my timezone it should be <date>2010-05-29T10:30:00+10</date> (replacing "Z" with my timezone offset). All of my attempts at reading such dates into my iPhone app have had the plist rejected as if it is malformed & editing a plist with such a date in Apple's editors changed the "+10" to "Z" without adjusting the time. Do others think I'm correct in thinking this is a bug in either plist or Xcode? My feeling is that the implementation of ISO date & time in plist is incomplete. Cheers, Pedro :)

  • collection_select not working as expected

    - by kgb
    First time I've come to use collection_select in a project and I've hit a wall with it. A Profile has_one Team, Team has_many Profile. In my view for editing profiles I have this. <td><%= f.collection_select(:team_id, @team, :id, :title) %></td> Which populates the drop down with titles of teams as expected. The couple of examples I have read seem to use it in a very similar way. I can't figure out when the profile is saved why it isn't populating the team_id field in my DB. In the development log the team_id is being passed. Processing ProfilesController#update (for 127.0.0.1 at 2010-03-28 22:49:16) [PUT] Parameters: {"commit"=>"Update", "profile"=>{"dob(1i)"=>"2010", "second_name"=>"", "dob(2i)"=>"3", "role"=>"", "dob(3i)"=>"28", "project"=>"", "specialties"=>"", "about"=>"", "team_id"=>"1", "status"=>"", "first_name"=>""}, "authenticity_token"=>"sdTiFPGj9JCO3OEge5EGNGxZbQSsq9ME5LP342EBjyc=", "id"=>"3"} The update controller is the standard scaffold one, this has worked fine for all other additions to the profile model I'd made previously. Am I missing something obvious?

  • Highlighting correctly in an emacs major mode

    - by Paul Nathan
    Hi, I am developing an emacs major mode for a language (aka mydsl). However, using the techniques on xahlee's site doesn't seem to be working for some reason (possibly older emacs dialect..) The key issues I am fighting with are (1) highlighting comments is not working and (2), the use of regexp-opt lines is not working. I've reviewed the GNU manual and looked over cc-mode and elisp mode... those are significantly more complicated than I need. ;;;Standard # to newline comment ;;;Eventually should also have %% to %% multiline block comments (defun mydsl-comment-dwim (arg) "comment or uncomment" (interactive "*P") (require 'newcomment) (let ((deactivate-mark nil) (comment-start "#") (comment-end "") comment-dwim arg))) (defvar mydsl-events '("reservedword1" "reservedword2")) (defvar mydsl-keywords '("other-keyword" "another-keyword")) ;;Highlight various elements (setq mydsl-hilite '( ; stuff between " ("\"\\.\\*\\?" . font-lock-string-face) ; : , ; { } => @ $ = are all special elements (":\\|,\\|;\\|{\\|}\\|=>\\|@\\|$\\|=" . font-lock-keyword-face) ( ,(regexp-opt mydsl-keywords 'words) . font-lock-builtin-face) ( ,(regexp-opt mydsl-events 'words) . font-lock-constant-face) )) (defvar mydsl-tab-width nil "Width of a tab for MYDSL mode") (define-derived-mode mydsl-mode fundamental-mode "MYDSL mode is a major mode for editing MYDSL files" ;Recommended by manual (kill-all-local-variables) (setq mode-name "MYDSL script") (setq font-lock-defaults '((mydsl-hilite))) (if (null mydsl-tab-width) (setq tab-width mydsl-tab-width) (setq tab-width default-tab-width) ) ;Comment definitions (define-key mydsl-mode-map [remap comment-dwim] 'mydsl-comment-dwim) (modify-syntax-entry ?# "< b" mydsl-mode-syntax-table) (modify-syntax-entry ?\n "> b" mydsl-mode-syntax-table) ;;A gnu-correct program will have some sort of hook call here. ) (provide 'mydsl-mode)

  • ActionScript : Applying frame to a image / background?

    - by Jay
    I am editing a custom calendar application in flash. The purpose of this app is to let you select your own images, and create a calendar out of it. You can basically, drag and drop images of your choice and they apply frame/borders, or drag and drop embellishments. Here is the piece of code that draws a border/frame on the embellishment/image of your choice. tempListener.onLoadInit = function(target_mc:MovieClip) { var mcName = target_mc._name.substring(0, target_mc._name.indexOf("@", 0)); if(mcName == "frame_Image") { target_mc.onPress = function() { if(_root.selectedImage != null) { var index = this._name.substring(this._name.indexOf("@",0)+1, this._name.length); var objPath = nodesFrames.childNodes[index-1].attributes.image; if(_root.selectedImage._name.split("@")[0] == "image") { var mask = _root.selectedImage[_root.selectedImage._parent._name + "_" + _root.selectedImage._name + "_maskMc"]; frameImageWidth = mask._width; frameImageHeight = mask._height; frameImageXScale = -1; frameImageYScale = -1; } else { frameImageXScale = _root.selectedImage._xscale; frameImageYScale = _root.selectedImage._yscale; _root.selectedImage._xscale = 100; _root.selectedImage._yscale = 100; frameImageWidth = _root.selectedImage._width; frameImageHeight = _root.selectedImage._height; } if(_root.selectedImage["frame"]) {} else { _root.selectedImage.createEmptyMovieClip("frame", _root.selectedImage.getNextHighestDepth()); } var image_mcl1:MovieClipLoader = new MovieClipLoader(); image_mcl1.addListener(_root.mclFrameListener); image_mcl1.loadClip("Images/" + objPath, _root.selectedImage["frame"]); } } } I need to somehow apply the chosen frame image, to the entire background - not just to the embellishment or image. How do I go about this? Thanks in advance for your inputs. Please let me know if the question doesn't make sense, I will attach some images that can help you with the context.

  • Quick MVC2 checkbox question

    - by kevinmajor1
    In order to get my EF4 EntityCollection to bind with check box values, I have to manually create the check boxes in a loop like so: <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" /><br /> <% } %> </p> It works, but it doesn't automatically populate the group of check boxes with existing values when I'm editing a model entity. Can I fudge it with something like? <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" checked=<%: Model.GameData.Platforms.Any(p => PlatformID == i) ? "true" : "false" %> /><br /> <% } %> </p> I figure there has to be something along those lines which will work, and am just wondering if I'm on the right track. EDIT: I'm purposely staying away from MVC's check box HTML helper methods as they're too inflexible for my needs. My check boxes use integers as their values by design.

  • How to apply CSS theme to only a specific jQuery-UI element?

    - by Thierry-Dimitri Roy
    I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.

  • White Screen of Death (WSOD) in Browser

    - by nickyt
    Here's the specs: ASP.NET 3.5 using ASP.NET AJAX AJAX Control Toolkit jQuery 1.3.2 web services IIS6 on Windows Server 2003 SP1 SP1 SQLServer 2005 SP3 Site is SSL Here's the problem: I'm getting the White Screen of Death (WSOD) in pretty much any browser (at least FireFox and IE 7/8). We have an application that uses one popup window for updating records. Most of the time when you click on the [Edit] button to edit a record, the popup window opens and loads the update page. However, after editing records for a while, all of a sudden the popup window will open, but it stays blank and just hangs. The URL is in the address bar. Loading up Fiddler I noticed that the request for the update page is never sent which leads me to believe it's some kind of lockup on the client-side. If I copy the same URL that's in the popup window into a new browser window, the page generally loads fine. Observations: - Since the request is never sent to the server, it's definitely something client-side - Only appears to happen when there is some semblance of traffic on the site which is weird because this appears to be contained within client-side code - There is a web service being called in the background every few seconds checking if the user is logged on, but this doesn't cause the freeze. I'm really at a loss here. I've googled WSOD but not much seems to appear related to my specific WSOD. Any ideas?

  • Is there a simple way to "roll your own forms" for mysql in php, for example in jquery?

    - by talkingnews
    I've been googling around for a really simple way of making what is, in effect, nothing more than an enhanced phpMySql. In a mysql database, I have: Name, address, phone, website etc, plus 2 or 3 custom fields. This data is pulled out to make a website. All I want is to be able to make a freeform form, a bit like Access, but for the web, and the only thing I want to do over and above normal field editing would be to have a list of when I contact them, what was said, and perhaps a reminder when the next action is due. I've looked at so many CRMs my mind is boggling, and they all do WAY more than I need. I don't have leads or accounts, all I have is the need to make sure than when I update the person's details, and for that data to be in the same DB as my site is generate from. I'm happy to learn if I can get pointed in the right direction, and I have a feeling that something like what I want might lie in the direction of jquery. It's just that there's so much good jquery stuff about, I can't see the wood for the trees! Thanks.

  • Hashing the state of a complex object in .NET

    - by Jan
    Some background information: I am working on a C#/WPF application, which basically is about creating, editing, saving and loading some data model. The data model contains of a hierarchy of various objects. There is a "root" object of class A, which has a list of objects of class B, which each has a list of objects of class C, etc. Around 30 classes involved in total. Now my problem is that I want to prompt the user with the usual "you have unsaved changes, save?" dialog, if he tries to exit the program. But how do I know if the data in current loaded model is actually changed? There is of course ways to solve this, like e.g. reloading the model from file and compare against the one in memory value by value or make every UI control set a flag indicating the model has been changed. Now instead, I want to create a hash value based on the model state on load and generate a new value when the user tries to exit, and compare those two. Now the question: So inspired of that, I was wondering if there exist some way to generate a hash value from the (value)state of some arbitrary complex object? Preferably in a generic way, e.g. no need to apply attributes to each involved class/field. One idea could be to use some of .NET's serialization functionality (assuming it will work out-of-the-box in this case) and apply a hash function to the content of the resulting file. However, I guess there exist some more suitable approach. Thanks in advance.

  • How to get a template tag to auto-check a checkbox in Django

    - by Daniel Quinn
    I'm using a ModelForm class to generate a bunch of checkboxes for a ManyToManyField but I've run into one problem: while the default behaviour automatically checks the appropriate boxes (when I'm editing an object), I can't figure out how to get that information in my own custom templatetag. Here's what I've got in my model: ... from django.forms import CheckboxSelectMultiple, ModelMultipleChoiceField interests = ModelMultipleChoiceField(widget=CheckboxSelectMultiple(), queryset=Interest.objects.all(), required=False) ... And here's my templatetag: @register.filter def alignboxes(boxes, cls): """ Details on how this works can be found here: http://docs.djangoproject.com/en/1.1/howto/custom-template-tags/ """ r = "" i = 0 for box in boxes.field.choices.queryset: r += "<label for=\"id_%s_%d\" class=\"%s\"><input type=\"checkbox\" name=\"%s\" value=\"%s\" id=\"id_%s_%d\" /> %s</label>\n" % ( boxes.name, i, cls, boxes.name, box.id, boxes.name, i, box.name ) i = i + 1 return mark_safe(r) The thing is, I'm only doing this so I can wrap some simpler markup around these boxes, so if someone knows how to make that happen in an easier way, I'm all ears. I'd be happy with knowing a way to access whether or not a box should be checked though.

  • python gui events out of order

    - by dave
    from Tkinter import * from tkMessageBox import * class Gui: def __init__(self, root): self.container = Frame(root) self.container.grid() self.inputText = Text(self.container, width=50, height=8) self.outputText = Text(self.container, width=50, height=8, bg='#E0E0E0', state=DISABLED) self.inputText.grid(row=0, column=0) self.outputText.grid(row=0, column=1) self.inputText.bind("<Key>", self.translate) def translate(self, event): input = self.inputText.get(0.0, END) output = self.outputText.get(0.0, END) self.outputText.config(state=NORMAL) self.outputText.delete(0.0, END) self.outputText.insert(INSERT, input) self.outputText.config(state=DISABLED) showinfo(message="Input: %s characters\nOutput: %s characters" % (len(input), len(input))) root = Tk() #toplevel object app = Gui(root) #call to the class where gui is defined root.mainloop() #enter event loop Working on a gui in tkinter I'm a little confused as to the sequence the event handlers are run. If you run the above code you'll hopefully see... 1) Editing the text widget triggers the event handler but it seems to fire it off without registering the actual change, 2) Even when the text widget is cleared (ie, keep pressing BackSpace) it still seems to have a one character length string, 3) The output widget only receives its update when the NEXT event trigger is fired despite the fact the data came on the previous event. Is this just how bindings work in tkinter or am i missing something here? The behaviour i would like when updating the input widget is: 1) Show the change, 2) Enter event handler, 3) Update output widget, 4) Show message box.

  • Compiling a click-once app that requires administrator?

    - by Assimilater
    Hi, a lot of my programs require the ability to write files to the hard drive. When I first made these programs for XP they worked great. Now I'm less ignorant about UAC (got a new laptop recently). And for future customers...I've noticed the potential for a LOT of annoying error messages....and quite frankly if the program can't write data to the hard drive or thumb drive it's on...there's no point to running it.... I've tried multiple times to build in the manifest a requirement for administrator or user access....I'm not sure if anything less would solve the problem...but have failed because click-once has security features in place to prevent me from doing so. I'd rather not have to tell my customers how to make the program run as an administrator by editing the file's properties...I'd much rather have a convenient pop up like what you'd see new programs such as Itunes or Filezilla show if they were in conflict with UAC requesting the privileges they need. I'd really like to do this but have had little success. Any and all advice that can remedy this grievous problem appreciated. Thanks.

  • about c# OBJECTS and the Possibilties it has.

    - by user527825
    As a novice programmer and i always wonder about c# capabilities.i know it is still early to judge that but all i want to know is can c# do complex stuffs or something outside windows OS. 1- I think c# is a proprietary language (i don't know if i said that right) meaning you can't do it outside visual studio or windows. 2-also you cant create your own controller(called object right?) like you are forced to use these available in toolbox and their properties and methods. 3-can c# be used with openGL API or DirectX API . 4-Finally it always bothers me when i think i start doing things in visual studio, i know it sounds arrogant to say but sometimes i feel that i don't like to be forced to use something even if its helpful, like i feel (do i have the right to feel?) that i want to do all things by myself? don't laugh i just feel that this will give me a better understanding. 5- is visual c# is like using MaxScript inside 3ds max in that c# is exclusive to do windows and forms and components that are windows related and maxscript is only for 3d editing and manipulation for various things in the software. If it is too difficult for a beginner i hope you don't answer the fourth question as i don't have enough motivation and i want to keep the little i have. thank you for your time. Note: 1-sorry for my English, i am self taught and never used the language with native speakers so expect so errors. 2-i have a lot of questions regarding many things, what is the daily ratio you think for asking (number of questions) that would not bother the admins of the site and the members here. thank you for your time.

  • Best practice to structure large html-based project

    - by AntonAL
    I develop Rails based website, enjoying using partials for some common "components" Recently, i faced a problem, that states with CSS interference. Styles for one component (described in css) override styles for another components. For example, one component has ... <ul class="items"> ... and another component has it too. But that ul's has different meaning in these two components. On the other hand, i want to "inherit" some styles for one component from another. For example: Let, we have one component, called "post" <div class="post"> <!-- post's stuff --> <ul class="items"> ... </ul> </div And another component, called "new-post": <div class="new-post"> <!-- post's stuff --> <ul class="items"> ... </ul> <!-- new-post's stuff --> <div class="tools">...</div> </div Post and new-post have something similar ("post's stuff") and i want to make CSS rules to handle both "post" and "new-post" New post has "subcomponents", for example - editing tools, that has also: <ul class="items"> This is where CSS rules starting to interfer - some rules, targeted for ul.items (in post and new-post) applies subcomponent of new-post, called "tools" On the one hand - i want to inherit some styles On the other hand, i want to get better incapsulation What are the best practices, to avoid such kind of problems ?

  • Why is debugging better in an IDE?

    - by Bill Karwin
    I've been a software developer for over twenty years, programming in C, Perl, SQL, Java, PHP, JavaScript, and recently Python. I've never had a problem I could not debug using some careful thought, and well-placed debugging print statements. I respect that many people say that my techniques are primitive, and using a real debugger in an IDE is much better. Yet from my observation, IDE users don't appear to debug faster or more successfully than I can, using my stone knives and bear skins. I'm sincerely open to learning the right tools, I've just never been shown a compelling advantage to using visual debuggers. Moreover, I have never read a tutorial or book that showed how to debug effectively using an IDE, beyond the basics of how to set breakpoints and display the contents of variables. What am I missing? What makes IDE debugging tools so much more effective than thoughtful use of diagnostic print statements? Can you suggest resources (tutorials, books, screencasts) that show the finer techniques of IDE debugging? Sweet answers! Thanks much to everyone for taking the time. Very illuminating. I voted up many, and voted none down. Some notable points: Debuggers can help me do ad hoc inspection or alteration of variables, code, or any other aspect of the runtime environment, whereas manual debugging requires me to stop, edit, and re-execute the application (possibly requiring recompilation). Debuggers can attach to a running process or use a crash dump, whereas with manual debugging, "steps to reproduce" a defect are necessary. Debuggers can display complex data structures, multi-threaded environments, or full runtime stacks easily and in a more readable manner. Debuggers offer many ways to reduce the time and repetitive work to do almost any debugging tasks. Visual debuggers and console debuggers are both useful, and have many features in common. A visual debugger integrated into an IDE also gives you convenient access to smart editing and all the other features of the IDE, in a single integrated development environment (hence the name).

  • List of models in Model in MVC

I can see in logs that data is sent correctly. I have tried everything, nothing works.
