Integrating VichUploaderBundle to Upload Files and Images

The spec bundled binaries edit pdf tells PyInstaller how to process your script. It encodes the script names and most of the options you give to the pyinstaller command. The spec file is actually executable Python code. PyInstaller builds the app by executing the contents of the spec file.
For many uses of PyInstaller you do not need to examine or modify the spec file. It is usually enough to give all the needed information such as hidden imports as options to the pyinstaller command and let it run. The options are the same options documented above for the pyinstaller command.
This command creates the name. After you have created a spec file and modified it as necessary, you build the application by passing the spec file to the pyinstaller command:. When you create a spec file, most command options are encoded bundled binaries edit pdf the spec file.
When you build from a spec file, those options cannot be changed. If they are given on the command line they are ignored and replaced by the options in the spec file. After PyInstaller creates a spec file, or opens a spec file when one is given instead of a script, the pyinstaller command executes the spec file as code. Your bundled application is created by the execution of the spec file. The following is an shortened example of a spec file for a minimal, one-folder app:.
You modify the spec file to pass additional values to Analysis and to EXE. To add files to the bundle, you create a bundled binaries edit pdf that describes the files and supply it to the Analysis call. When you bundle to a single folder see Bundling to One Folderthe added data files are copied into the folder with the executable. This means that any changes a one-file executable makes to an added file will be lost when the application ends. In either case, to find the data files at run-time, see Run-time Information.
You can add data files to the bundle by using the --add-data command option, or by adding them as a list to the bundled binaries edit pdf file. The list of data files is a list of tuples. Each tuple has two values, both of which must be strings:. For example, to add a single README file to the top level of a one-folder app, you could modify the spec file as follows:.
And the command line equivalent see What to bundle, where to search for platform-specific details:. That file will be looked up relative to the location of the spec file and copied into the top level of the bundled app. For example to include all the. If the data files you are adding are contained within a Python module, you can retrieve them using pkgutils.
For example, suppose that part of your application is a module named helpmod. In the same folder as your script and its spec file you have this folder arrangement:. Because your script includes the statement import helpmodPyInstaller will create this folder arrangement in your bundled app. However, it will only include the. To cause it to be included also, you would add a datas tuple to the spec file:.
However, this data file is part of a module, so you can also retrieve its contents using the standard library function pkgutil. If it is actually characters, you must decode it:.
Binary files refers to DLLs, dynamic libraries, shared object-files, and such, which PyInstaller is going to search for further binary dependencies.
Files like images and PDFs should go into the datas. You can add binary files to the bundle by using the --add-binary command option, or by adding them as a list to the spec file. In the spec file, make a list of tuples that describe bundled binaries edit pdf files needed. Normally PyInstaller learns about. But even that might not find all dependencies. PyInstaller does not find this dependency. You could add it to the bundle this way:.
Or via the command line again, see What to bundle, where to search for platform-specific details:. As with data files, if you bundled binaries edit pdf multiple binary files to add, create the list in a separate statement and pass the list by name. PyInstaller supports a more advanced and complex way of adding files to the bundle that may be useful for special cases. You can pass command-line options to the Python interpreter.
The interpreter takes a number of bundled binaries edit pdf options but only the following are supported for a bundled app:. To pass one or more of these options, create bundled binaries edit pdf list of tuples, one for each option, and pass the list as an additional argument to the EXE call. Each tuple has three elements:. See the Apple bundle overview for a discussion of the contents of Info. PyInstaller creates a minimal Info.
The value of this argument is a Python dict. Each key and value in the dict becomes a key and value in the Info. It cannot handle nested XML arrays. For example, if you want to modify Info.
Bundled binaries edit pdf value of that keyword is a list of dicts, each bundled binaries edit pdf up to five key: However, when you re-run PyInstalleryour changes will be wiped out. One solution is to prepare a complete Info. Begin by building and testing the windowed app. When it works, copy the Info. This includes the CFBundleExecutable value as well as the icon path and bundle identifier if you supplied them. From that point on, to rebuild the app call PyInstaller in a shell script, and follow it with a statement such as:.
This feature is broken in the PyInstaller 3. Do not attempt building multipackage bundles until the feature is fixed. If this feature is important to you, follow and comment on PyInstaller Issue Some products are made of several different apps, each of which might depend on a common set of third-party libraries, or share code in other ways. When packaging such an product it would be a pity to treat each app in isolation, bundling it with all its dependencies, because that means storing duplicate copies of code and libraries.
You can use the multipackage feature to bundle a set of executable apps so that they share bundled binaries edit pdf copies of libraries. You can do this with either one-file or one-folder apps.
Each dependency a DLL, for example is packaged only once, in one of the apps. This saves disk space because each dependency is stored only once. However, to follow an external reference takes extra time when an app is starting up. All but one of the apps in the set will have slightly slower bundled binaries edit pdf times.
The external references between binaries include hard-coded paths to the output directory, and cannot be rearranged. If you use one-folder mode, you must install all the application folders within a single parent directory.
If you use one-file mode, you must place all the related applications in the same directory when you install the application. To build such a set of apps you must code a custom spec file that contains a call to the MERGE function. This function takes a list of analyzed scripts, finds their common dependencies, and modifies the analyses to minimize the storage cost. The order of the analysis objects in the argument list matters. The MERGE function packages each dependency into the first script from left to right that needs that dependency.
A script that comes later in the list and needs the same file will have an external reference to the prior script in the list. You might sequence the scripts to place the most-used scripts first in the list. Its variable-length list of arguments consists of a list of tuples, each tuple having three elements:. It modifies these objects to avoid duplication of libraries and modules. As a result the packages generated will be connected.
One way to construct a spec file for a multipackage bundle is to first build a spec file for each app in the package. Suppose you have bundled binaries edit pdf product that comprises three apps named because we have no imagination foobar and zap:.
Check for warnings and test each of the apps individually. Deal with any hidden imports and other problems. When all three work correctly, combine the statements from the three files foo. First copy the Analysis statements bundled binaries edit pdf each, changing them to give each Analysis object a unique name:.
Save the combined spec file as foobarzap. Remember that a spec bundled binaries edit pdf is executable Python. While a spec file is executing it has access to a limited set of global names. These names include the classes defined by PyInstaller: The following is an shortened example of a spec bundled binaries edit pdf for a minimal, one-folder app: Each tuple has two values, both of which must be strings: The first string specifies the file or files as they are in this system now.
