I've set up Contentful as the headless CMS of my blog. Everything works, except rendering assets (in my case images specifically). My blog is built using Symfony and uses Twig for templating.
This is how (a part of the) content is currently rendered:
I'm using Contentful's default rich text renderer for Twig, as described here. Unfortunately, it doesn't say anything about assets. But given that there's an EmbeddedImage class available, I would expect support for images.
What step am I missing?
You need to define a custom renderer for the assets in the same way as described for a custom heading here.
The reason why assets don't work "out of the box" is that the renderer can't know what type of asset is being returned. For example, is it a .jpg, .mp4, .wav file etc. You may have a variety of different assets in your Rich Text and will need to render the different asset files accordingly to your HTML.
The full list of node types you can define custom renderers for is here.

Using 2sxc on DNN, I have a website that uses SVGs for icons in content types. The client wants to be able to upload the SVG icons to 2sxc via a Link field but then instead of rendering <img src="#Content.SVG" />, they want it to render the source code of the SVG (so we could manipulate the fill color via CSS). Is this even possible and how could it be done?
Basically 2 steps
Get the real file name using 2sxc and DNN
Then load the file as a string using normal .net stuff System.IO and add it to your html - https://learn.microsoft.com/en-us/dotnet/api/system.io.file.readalltext?view=netframework-4.5.1
ca. like this
<div>
#Html.Raw(System.IO.File.ReadAllText(fileName)
</div>
Some examples of how to do this can be found below
Using the fetch API
How to convert image (svg) to rendered svg in javascript?

Include SVG files with HTML, and still be able to apply styles to them?
Using D3
(Embed and) Refer to an external SVG via D3 and/or javascript
Using a custom JS library
One example: SVGInjector
Interestingly Dnn is doing this nowadays and you can look at the code here. If you ignore the caching, you might be able to do similar in a View.
https://github.com/dnnsoftware/Dnn.Platform/blob/0d3b931d8483b01aaad0291a5fde2cbc0bac60ca/DNN%20Platform/Website/admin/Skins/Logo.ascx.cs#L123
And that is called from above, see ~line 71, so they are doing a real inject of the file contents to inline. Obviously caching file-access stuff should be a priority for caching if the website is high-traffic, but otherwise it is not needed or at least secondary.
I am trying to use a 3rd party javascript control, Owl Carousel. The way I am reading the documentations is this:
In the zip file from Owl Carousel there is a folder called owlcarousel that contains the javascript and another folder that contains all the supporting files which need to be copied to /modules/base-accelerator/yacceleratorstorefront/web/webroot/_ui/responsive/common. Then I simply need to go into the javaScript.tag file and add this line towards the end of the file:
<script src="${commonResourcePathHtml}/owlcarousel/owl.carousel.min.js"></script>
Upon trying that, I get all sorts of loading errors and no images are display, even without using the control. So my question is:
What is the correct approach to include a 3rd party javascript?
Is there any way to control which pages actually get a javascript file or do simply ALL the pages get ALL the javascript includes?

I am using orchard cms with the bootstrap theme.
I have created a content type: House
it contains FIELDS
image (media picker field)
Property Type (taxonomy field)
Location (taxonomy field)
It has PARTS
common
body
publish later
Title
Autoroute
I want queries of houses and be able to choose the view/ layout for them
e.g. layout called HouseList (for sidebars mainly) which will render: title, image and link to house, possible location and type but with out the links as defaulted. And then a fullDetails layout and a image only layout (so i can show a jquery image reel a widget say in a quadzone) How can i do all this please, i have tried in view Content-House.cshtml etc but i cant access the details model.content to choose what to display.
Im sure when i get the idea of how to do 1 i should be able to sort the rest. I have read documentation etc but there are so many different ways, ie placement file, change the parts, contents, create classes to handle display etc. sureley i am missing something simple like create a view for each list i want eg. houue-list, house-details, house-imageONly and then manipulate content.
Please help i have been trying different things for getting this site running for weeks and not getting very far. Examples would be fantastic but i have searched google for hours and found similar but nothing with enough details for a meer beginer.
Thanks
The standard way of doing that is placement to move things around and alternate templates for the different parts and fields. You can specialize placement and alternates with the display type, which is Summary when rendering in a list such as what a projection returns, and Detail for the detail view. More info on placement can be found here: http://docs.orchardproject.net/Documentation/Understanding-placement-info and on alternates here: http://docs.orchardproject.net/Documentation/Alternates
Now if you prefer to completely take over the rendering and do without placement, here are a few posts that may help:

I've just started developing in express and am new to Jade as well.
I'm having trouble deciding when it's appropriate to use layouts and when not to. I'm also having trouble deciding when it's appropriate to use something like blocks vs. partials.
Any help regarding this is truly appreciated. I'm a little lost.
It's mostly a matter of preference. If you are used to something like Wordpress where you have a concept of a header and footer that you include into pages than you might not like layouts. I personally only use layouts with content blocks because the non-layout way tends to cause more repetition.
As for partials vs blocks. You use a partial for items that you want to reuse on different pages. While a block is a chunk of html that will be replaced by child templates.
An example of a partial can be the html for a product. So you have a thumbnail, the title and a description of a product. You might use this partial while listing the products in a category. But you might also use this partial for rendering a list of search results.
An example of a partial can be a main layout that contains you header and your navigation and a content area. If you want to reuse this main layout on multiple pages you will extend this it and overwrite the block in the child templates.
My objective is to generate a graphic layout (made of Richfaces components) based on some input configuration (like an XML file) and display it in my web app. The layout is composed of graphic symbols representing various entities in the system: each symbol should be mapped to an entity in the system, in order to display its state. The XML configuration file is used to define the symbol connections and positions within the layout, and their mapping rules to an entity. How can I achieve this?
I was thinking to create a symbol library in a technology such as SVG, where you can define both the aspect and the behaviour, and then simply "wrap" each SVG symbol in a dynamically created richfaces component, which would allow me to handle both the user interactions and the mapping rules defined in the symbol. Unfortunately JSF/Richfaces don't support SVG images, therefore I would have to use plain HTML without Richfaces features.
Another way to achieve that would be to simply define generic symbols in the XML file, each one of them with an attribute specifying the related image, the mapping rule, etc., and then generate the corresponding richfaces component from within the web-app. By doing so, would I be able to then display all the symbols in the right position and therefore generate the complete dynamic layout?
Could you suggest a better approach? Thank you very much.
I believe that HTML5 has direct support for SVG images, however it is still an embedded object in regular HTML after all. This too is something I have been waiting for however I don't believe any of the current JSF2 component libraries have an offerring for this yet.
Here is a good explanation of a possible workaround:
Getting started with SVG graphics objects in JSF 2.0 pages
Potentially you could build a custom facelet component utilizing this workaround?
My thought though is that when your only tool is a hammer, everything looks like a nail. I would try to utilize an RIA (Rich Internet Application) technology better suited for display and manipulation of vector graphics like HTML5, Flash+Flex, Silverlight, etc..
