Product page fails to render

When you click on a product page, it only shows a one image. Looking at the stack trace, it looks like there is some PHP error. I think when I patched to 2.3.2, maybe something didn’t updated? How do I recover?

eg. click the product, then it is only the product image showing afterwards. enter image description here

<div class="gallery-placeholder _block-content-loading" data-gallery-role="gallery-placeholder"> <img alt="main product photo" class="gallery-placeholder__image" src="" /> </div>  <script type="text/x-magento-init"> { "[data-gallery-role=gallery-placeholder]": { "mage/gallery/gallery": { "mixins":["magnifier/magnify"], "magnifierOpts": {"fullscreenzoom":"5","top":"","left":"","width":"","height":"","eventType":"hover","enabled":false}, "data": [{"thumb":"https:\/\/\/pub\/media\/catalog\/product\/cache\/155e93c92386e3c82347ea16620ccbd3\/j\/b\/jb-rebuild_1000x1000.png","img":"https:\/\/\/pub\/media\/catalog\/product\/cache\/85991805028918d3c76d0ac026e0a79d\/j\/b\/jb-rebuild_1000x1000.png","full":"https:\/\/\/pub\/media\/catalog\/product\/cache\/8626c40ec5098cb7aa441a37fc63fc11\/j\/b\/jb-rebuild_1000x1000.png","caption":"SteamSpeed Journal Bearing Rebuild Kit for MHI Compatible CHRA","position":"1","isMain":true,"type":"image","videoUrl":null}], "options": <br /> <b>Fatal error</b>: Uncaught Error: Call to a member function getOptionsJson() on null in /var/www/vhosts/ Stack trace: #0 /var/www/vhosts/ include() #1 /var/www/vhosts/ Magento\Framework\View\TemplateEngine\Php-&gt;render(Object(Magento\Catalog\Block\Product\View\Gallery\Interceptor), '/var/www/vhosts...', Array) #2 /var/www/vhosts/ Magento\Framework\View\Element\Template-&gt;fetchView('/var/www/vhosts...') #3 /var/www/vhosts/ Magento\Catalog\Block\Product\View\Gallery\Interceptor-&gt;fetchView('/var/www/vhosts...') #4 /var/www/vhosts/ in <b>/var/www/vhosts/</b> on line <b>48</b><br /> 

SharePoint 2013 – Render Page in iFrame without Navigation Elements?

I’m in a SP environment that is tightly controlled and for instance don’t have access to Designer.

I’m attempting to setup a page to have the user select contents from buttons, which will then load those ‘content’ pages into an iFrame. I have a test case setup and working. However, when I click a button and a page loads within the iFrame it brings with it the global navigation and left menu bar. I’ve tried:

1) Appending ?Dlg=1 to the URLs. No change.

2) Applying following code to the

<style type="text/css">      #s4-ribbonrow, .ms-cui-topBar2, .s4-notdlg, .s4-pr s4-ribbonrowhidetitle, .s4-notdlg noindex, #ms-cui-ribbonTopBars, #s4-titlerow, #s4-pr s4-notdlg s4-titlerowhidetitle, #s4-leftpanel-content {display:none !important;}      .s4-ca{margin-left:0px !important; margin-right:0px !important;}  </style> 

3) Applying following code through CWEP, but SP keeps overwriting it.

<style> .ms-core-navigation { DISPLAY: none } #contentBox { margin-left: 0px } </style> 

Any help would be appreciated!

M2: flushing cache lets page render one time, then blank white page thereafter

I’m working through Alan Storm’s ‘No Frills Magento 2 Layout’ an internal dev server. He walks the reader through small edit, refresh, another small edit, refresh, see what changes, and so on. There are lots of examples. Then I inserted a typo which I couldn’t find, that ended up being whitespace added at the end of 'Magento\Framework\View\Element\Template ' when I copied and paste from the PDF manual.

I then sorted out getting errors enabled, however I managed to get the Magento 2.3.2 install into a bad state where there are white pages on every refresh. Clean the cache and hit F5, the site comes back, but for only one render.

This was a fresh install and I had only executed php bin/magento deploy:mode:set developer as per the install instructions for the module which is part of the book.

I then started an exploration of every command available from the internet in an attempt to be able to hit F5 and just get a page to reload. I issued these two commands:

php bin/magento deploy:mode:set developer php bin/magento cache:disable 

And now the site will refresh with F5 but instead of quickly refreshing, the server grinds for 7 to 10 seconds and then renders Hello World

What mechanism in Magento 2 causes this?
What can a person do to get back to how the site was working as expected before all this?

Right now, I believe the solution is to move this M2 and start over by installing a new fresh instance. But that simply is not acceptable; what happens if a live site starts acting like this? Having to clean cache to render one page is not acceptable nor is disabling cache…

Shiny: Render dynamic number of images from destination

I need to render dynamic number of images from destination. But as the result through the loop I render several times only the last image from destination. But all images must be different.

My solution is inspired by these answers from stackoverflow

Shiny: Dynamic Number of Output Elements/Plots

dynamically add plots to web page using shiny

library(shiny)  # get all files from destination images <- list.files("charts") image_names <- str_replace_all(images, ".png", "")   server <- shinyServer(function(input, output) {     output$  images <- renderUI({      image_output_list <-        lapply(1:length(image_names),              function(i)              {                imagename = paste0(image_names[i], "_image")                imageOutput(imagename)                )                }), image_output_list)   })    observe({     # if(is.null(input$  files)) return(NULL)     for (i in 1:length(image_names))     {       print(i)       local({         imagename <- paste0(image_names[i], "_image")         print(imagename)         output[[imagename]] <-            renderImage({             list(src = normalizePath(paste0('charts/', image_names[i], '.png')))           }, deleteFile = FALSE)       })     }   })  })  ui <- shinyUI(fluidPage(   titlePanel("Sidebar"),   sidebarLayout(     sidebarPanel(),     mainPanel(       uiOutput('images')     )   ) ))  shinyApp(ui=ui,server=server) 

Would it be reasonable to use the HTML Canvas as a render solution for a app on mobile?

This is my first post on this community, so let me know if I need to elaborate. I am making a motion graphics app on mobile (think After Effects for iOS), and was wondering if it would be viable to use an HTML canvas for the render/preview portion (UI still uses Cocoa). I have laid out some pros:

  • I am already experienced in HTML5 canvas
  • I would not have to create a whole render engine
  • Creating new effects would be easier for me and other developers (less worrying about making libraries for effect developers)
  • I can render the final video using CaptureStream

What would be some possible cons, and, if impractical, what framework would apply for this situation? Would I just have to make my own engine from scratch?

Modify Unity’s New 2D Renderer for the Lighweight Render Pipeline

I would like to use the new 2D renderer available with the LWRP to take advantage of the 2D lights.

I would also like to replicate the things in this video – basically, I want my character to be visible through walls and when it is occluded.

The video uses the Forward Renderer to add the depth features, but there is no such thing in the properties of the 2D Renderer. Is it possible to both use the new 2D lights and use renderer features?

How to use Matplotlib’s Animation to Render Custom Open AI Gym Environment

I’m working on creating a new OpenAI Gym Environment and want to display a live animation that I have coded to display using Matplotlib.

I’ve tried plotting and calling in the render method but this creates a new window for each frame, and the old one window to be closed for the new one to open.

My current code for making the animation:

fig = plt.figure(figsize=(10,10), dpi=80)  plt.axis([0, SIZE, 0, SIZE]) plt.xticks([]) plt.yticks([])  plt.hist2d(x,y, bins=10, range=[[0, SIZE], [0, SIZE]]) sc, = plt.plot(x, y, 'ro')  # Plot boids def plot_boids(boids):   x = []   y = []    for boid in boids:     x.append(boid.x[0])     y.append(boid.x[1])    plt.hist2d(x,y, bins=10, range=[[0, SIZE], [0, SIZE]])   return sc.set_data(x, y)  def animate(i):   # ... compute some stuff here ...    fig = plot_boids(boids)  anim=animation.FuncAnimation(fig, animate, repeat=False,                                blit=False, frames=100, interval=100)  

Is there any way I can integrate the plt animation method directly into the render method for gym?
